Highlight predicate condition_variable::wait() method in condition_variable
front matter.
Rewrite the explanation of wait()'s Precondition.
Add a condition_variables subsection about no spurious condition_variable
wakeups. Remove "or spuriously" from wakeup conditions in wait*() methods.
First pass through "spurious wakeup" section in Rationale.
First pass through migration.qbk. Use lock_t throughout work_sharing.cpp,
instead of lock_t, lock_count and explicit std::unique_lock<std::mutex>
declarations. Unify treatment of main and dispatcher fibers.
Clarify thread-safety requirements on sched_algorithm::notify() and
suspend_until().
Clarify disable_interruption when rethrowing fiber_interrupted.
Consolidate future<T>::get(): returns T whether T is R, R& or void.
Mention nesting of disable_interruption (which matters) versus nesting of
restore_interruption (which doesn't). Mention that a disable_interruption
constructed within the scope of another disable_interruption is a no-op, both
itself and when passed to restore_interruption.
When packaged_task::operator()() stores a value or an exception, state "as if"
by promise::set_value() or set_exception(): the shared state is set ready.
Similarly for ~packaged_task() and ~promise() setting broken_promise.
Sprinkle links to the Allocator concept, std::allocator and
std::allocator_arg_t where referenced. Similarly for StackAllocator.
Add more cross-reference links where Fiber classes and methods are mentioned.
Also things like std::unique_lock and std::mutex.
Clarify error condition for value_pop() when channel is close()d.
Since fiber_specific_ptr::release() does not invoke cleanup, it should not
throw an exception raised during cleanup.
Add a note to the condition_variable::wait_for(..., pred) overload.
fiber_specific_ptr::reset() has no default argument.
Remove mention of launch policy deferred, since no API accepts a launch
policy argument.
Copy construction or copy assignment of a shared_future leaves other.valid()
unchanged. It won't be 'true' unless it was 'true' before.
Mention that [shared_]future::get_exception_ptr() does not invalidate.
Note that 'blocks' and 'suspends' are used interchangeably.
Add some cross-references; add link to std::allocator_arg_t. Clarify the
cross-reference to the paragraph describing BOOST_FIBERS_NO_ATOMICS.
Reformat some overly-long source lines.
