**                                                  **
** A simple mutual exclusion lock for use in apps   **
**   running on multiple threads that wish to       **
**   synchronize access to data or critical code    **
**   sections.  Calling Acquire() stalls the thread **
**   until the lock is free, Release() notifies     **
**   others that you are done, allowing another     **
**   thread access.                                 **
**                                                  **
** Note: This builds on pthreads!!                  **
