  SVN rev 200649 on 2009-12-17 20:41:40Z by jhb
  
  MFC 199606, 199614:
  Add an internal _once() method.  This works identical to pthread_once(3)
  with the additional property that it is safe for routines in libc to use
  in both single-threaded and multi-threaded processes.  Multi-threaded
  processes use the pthread_once() implementation from the threading library
  while single-threaded processes use a simplified "stub" version internal
  to libc.
