  "However if the external mutex is (or is layout compatible with) a
  pthread_mutex_t, then there is no need for the internal
  pthread_mutex_t. When one wants to wait, one simply waits on the
  external pthread_mutex_t with the internal pthread_cond_t."

This smells a little fishy.  It seems to imply that pthreads can wait
on any old data type that happens to be layout-compatible with
pthread_mutex_t.  Is that really true?
