    sys/kern             kern_proc.c 
  MFC rev. 1.241, 1.242, 1.243
  Add some Giant locks to protect against races between tty and sessrele(),
  doenterpgrp(), leavepgrp(), pgdelete() and enterpgrp(). The tty code is
  still under giant lock, but the session/pgrp release code just used
  proctree_locks. P_CONTROLT isn't really fully locked too in enterpgrp().
