  SVN rev 219378 on 2011-03-07 15:24:35Z by jh
  
  MFC r215687:
  
  Use g_eventlock to protect against losing wakeups in the g_event process
  and replace tsleep(9) with msleep(9) which doesn't use a timeout. The
  previously used timeout caused the event process to wake up ten times
  per second on an idle system.
  
  one_event() is now called with the topology lock held and it returns
  with both the topology and event locks held when there are no more
  events in the queue.
