Log Message:
- Get rid of self->pt_mutexhint and use pthread__mutex_owned() instead.
- Update some comments and fix minor bugs. Minor cosmetic changes.
- Replace some spinlocks with mutexes and rwlocks.
- Change the process private semaphores to use mutexes and condition
  variables instead of doing the synchronization directly. Spinlocks
  are no longer used by the semaphore code.
