  SVN rev 194771 on 2009-06-23 21:43:02Z by ed
  
  Improve my last commit: use a separate condvar to serialize.
  
  The advantage of using a separate condvar is that we can just use
  cv_signal(9) instead of cv_broadcast(9). It makes no sense to wake up
  multiple threads. It also makes the TTY code easier to understand.
  t_dcdwait sounds totally unrelated.
