BOOST_ASIO_STRAND_IMPLEMENTATIONS to the number.
Programs can now define BOOST_ASIO_ENABLE_SEQUENTIAL_STRAND_ALLOCATION to
switch the allocation of strand implementations to use a round-robin approach
rather than hashing.
Fix potential strand starvation issue that can occur when strand.post() is used.
[SVN r74955]

Explicitly specify the signal() function from the global namespace. Fixes#5722
Don't read the clock unless the heap is non-empty.

Make sure the synchronous null_buffers operations obey the user's non_blocking setting. Fixes#5756
Set size of select fd_set at runtime when using Windows.
Disable warning due to const qualifier being applied to function type.
Fix crash due to gcc_x86_fenced_block that shows up when using the Intel C++ compiler. Fixes#5763
Specialise operations for buffer sequences that are arrays of exactly two buffers.
Initialise all OpenSSL algorithms.
Fix error mapping when session is gracefully shut down.
Various performance improvements:
* Split the task_io_service's run and poll code.
* Use thread-local operation queues in single-threaded use cases (i.e. concurrency_hint is 1) to eliminate a lock/unlock pair.
* Only fence block exit when a handler is being run directly out of the io_service.
* Prefer x86 mfence-based fenced block when available.
* Use a plain ol' long for the atomic_count when all thread support is disabled.
* Allow some epoll_reactor speculative operations to be performed without holding the lock.
* Improve locality of reference by performing an epoll_reactor's I/O operation immediately before the corresponding handler is called. This also improves scalability across CPUs when multiple threads are running the io_service.
* Pass same error_code variable through to each operation's complete() function.
* Optimise creation of and access to the io_service implementation.
Remove unused state in HTTP server examples.
Add latency test programs.

* Fix include guard.
* Zero-length reads and writes need to complete immediately.
* Fix for static mutex initialisation.

[SVN r72847]
* Duration type should be signed in tick_count_timer example.
* Regenerate documentation.
* Make definition of BOOST_ASIO_MOVE_ARG and BOOST_ASIO_MOVE_CAST separate to
the definition of BOOST_ASIO_HAS_MOVE, to allow the latter to be user-defined.
[SVN r72404]
* On Windows, ensure the count of outstanding work is decremented for
abandoned operations (i.e. operations that are being cleaned up within
the io_service destructor).
* Fix basic_socket_streambuf compile error when using MSVC 10's std::array.
* Preserve the value of errno across the signal handler.
* Fix unused return value warning.
* Fix various minor documentation errors.
[SVN r70751]
* Improve backward compatibility of the new SSL implementation.
* Add wrapper for SSL_CTX_set_default_verify_paths().
* Document which OpenSSL functions the ssl::context member functions use.
* Add SSL certificate verification callbacks, and add a new
ssl::rfc2818_verification function object for simple peer certificate
verification based on the host name.
* Use std::atomic<> when available.
* Prefer to use std::array when it is available.
* Use std::shared_ptr and std::weak_ptr when available.
* Use a lightweight scoped smart pointer.
* Fix some shadow variable warnings with g++ 4.6.
[SVN r70384]
* Added support for C++0x move construction and assignment to sockets, serial
ports, POSIX descriptors and Windows handles.
* Regenerate documentation.
[SVN r70092]
* Fixed a compile error on some versions of g++ due to anonymous enums.
Fixes#4883.
* Fixed a bug in asio::streambuf where the consume() function did not
always update the internal buffer pointers correctly. The problem may
occur when the asio::streambuf is filled with data using the standard
C++ member functions such as sputn(). (Note: the problem does not
manifest when the streambuf is populated by the Asio free functions
read(), async_read(), read_until() or async_read_until().)
* EV_ONESHOT seems to cause problems on some versions of Mac OS X, with
the io_service destructor getting stuck inside the close() system
call. Use EV_CLEAR instead. Fixes#5021.
* Fixed a bug on kqueue-based platforms, where reactor read operations
that return false from their perform() function are not correctly
re-registered with kqueue.
* Fixed the linger socket option on non-Windows platforms.
* Fixed function name in comment for asio::placeholders::iterator.
[SVN r69680]
io_service.notify_fork() at the appropriate times. Two new examples have been
added showing how to use this feature. Refs #3238, #4162.
* Clean up the handling of errors reported by the close() system call. In
particular, assume that most operating systems won't have close() fail with
EWOULDBLOCK, but if it does then set blocking mode and restart the call. If
any other error occurs we assume the descriptor is closed. Refs #3307.
* EV_ONESHOT seems to cause problems on some versions of Mac OS X, with the
io_service destructor getting stuck inside the close() system call. Use
EV_CLEAR instead. Refs #5021.
* Include function name in exception what() messages.
* Fix insufficient initialisers warning with MinGW.
* Make the shutdown_service() member functions private.
* Add archetypes for testing socket option functions.
* Add missing lock in signal_set_service::cancel().
* Fix copy/paste error in SignalHandler example.
* The signal header needs to be included in signal_set_service.hpp so that we
can use constants like NSIG and SIGRTMAX.
* Don't use Boost.Thread's convenience header. Use the header file that is
specifically for the boost::thread class instead.
[SVN r69467]
* Added support for signal handling, using a new class called
signal_set. Programs may add one or more signals to the set, and then
perform an async_wait() operation. The specified handler will be
called when one of the signals occurs. The same signal number may
registered with multiple signal_set objects, however the signal number
must be used only with Asio.
* Added handler tracking, a new debugging aid. When enabled by defining
BOOST_ASIO_ENABLE_HANDLER_TRACKING, Asio writes debugging output to
the standard error stream. The output records asynchronous operations
and the relationships between their handlers. It may be post-processed
using the included [^handlerviz.pl] tool to create a visual
representation of the handlers (requires GraphViz).
* Fixed a bug in asio::streambuf where the consume() function did not
always update the internal buffer pointers correctly. The problem may
occur when the asio::streambuf is filled with data using the standard
C++ member functions such as sputn(). (Note: the problem does not
manifest when the streambuf is populated by the Asio free functions
read(), async_read(), read_until() or async_read_until().)
* Fixed a bug on kqueue-based platforms, where reactor read operations
that return false from their perform() function are not correctly
re-registered with kqueue.
* Modified the buffers_iterator<> and ip::basic_resolver_iterator
classes so that the value_type typedefs are non-const byte types.
