System-wide mutexes and pthreads

[Conrad Scott]

Looking at the current pthread implementation on cygwin, it seems that it
doesn't support any system-wide synchronization mechanisms (i.e. none of the
synchronization primitives allow PTHREAD_PROCESS_SHARED and there are no
named semaphores). Before I go and use win32 semaphores in the cygserver, is
there something I'm missing?

Cheers.
