    sys/kern             kern_exit.c 
  Log:
  Drop sched_lock around the wakeup of the parent process after setting
  the process state to zombie when a process exits to avoid a lock order
  reversal with the sleepqueue locks.  This appears to be the only place
  that we call wakeup() with sched_lock held.
