  Log:
  SVN rev 199606 on 2009-11-20 19:19:51Z by jhb
  
  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.  The libc stub-version of pthread_once() now also uses the
  simplified "stub" version as well instead of being a nop.
