  NOTES
         If more than one thread is blocked on a condition variable, the order
         in which threads are unblocked is determined by the scheduling policy.
  
  
!        USYNC_THREAD does not support multiple mapplings to the same logical
         synch object. If you need to mmap() a synch object to different
         locations within the same address space, then the synch object should
         be initialized as a shared object USYNC_PROCESS for Solaris, and
         PTHREAD_PROCESS_PRIVATE for POSIX.
