#8797: semaphores for boost.thread

     Type:  Patches           |     Status:  new
Milestone:  To Be Determined  |  Component:  thread
  Version:  Boost 1.55.0      |   Severity:  Problem

------------------------------+----------------------
 this patch adds support for semaphores to boost.thread.

 in addition to an emulation with mutex/condition_variable/counter, it
 provides native implementations for win32, posix and dispatch semaphores.
 the reason for adding native implementations is performance: they perform
 much better than an emulation. on osx, i have seen a speedup of 80 in
 microbenchmarks with strong contention.
