Make POSIX semaphores always process shared 
Python triggered the undefined behavior previously since it appears to
be posting to a semaphore owned by a different process that wasn't set
to process shared mode. The performance loss to process shared futexes
is so low and semaphores are generally used for this purpose, so it'll
be much simpler to simply not impose undefined behavior here.
