Not sure I understand the question.  What do you mean by S.O?  Are you saying 
that since the threads are POSIX, that you would expect the program to act 
the same on all Operating Systems?  That's not an entirely safe assumption to 
make in that POSIX only guarantees that things like mutexes work (and it 
specifically states that you have to unlock a mutex in the same thread you 
locked it, what you were doing would result in undefined behavior).  POSIX 
doesn't make any guarantees about how threads are scheduled with respect to 
one another.
