thread_pthread.h can be modified to use POSIX 
semaphores if available. This is more efficient than 
emulating them with mutexes and condition variables, 
and at least one platform that supports POSIX 
semaphores has a race condition in its condition 
variable support.

The new file would still be supporting POSIX threads, 
although from both <pthread.h> and <semaphore.h>, so 
perhaps ought to be renamed if this patch is accepted.

Can someone on a pthreads platform please continue with 
this?  I'm +1 on it via eyeballing.

Does this belong in the 2.2.x group?
