              Just about minimal example of the boost thread library
              using a typical pthread-like paradigm -- a paradigm that
              should make C programmers very comfortable.  Only the
              thread and mutex classes are demonstrated.  The idCnt
              and idMutex are window dressing just to make this
              program look like the other basic examples.
