  SVN rev 183179 on 2008-09-19 09:48:25Z by kib
  
  MFC r182193:
  Implement WNOWAIT flag for wait4(2). It specifies that process whose status
  is returned shall be kept in the waitable state.
  Add WSTOPPED as an alias for WUNTRACED.
  
  MFC r182424 (by davidxu):
  Don't remove queued SIGCHLD if options contain WNOWAIT, so other
  threads still can be notified by the signal.
