Duh.
sem_wait (wait for semaphore) is very different from pth_wait (wait for 
thread) `:)

pth supports mutex, rwlocks, condition variables and barriers.
Is there any chance I can do that with pth?
I have mit-pthreads already installed, can I do that with it?
Is there any real difference between different pthread implementations? 
Which is better??

Thank you for your attention.
