    sys/kern             kern_event.c 
  Log:
  MFC rev. 1.120:
  Kqueue_scan() may sleep when encountered the influx knotes. On the other
  hand, it may cause other threads to sleep since kqueue_scan() may mark
  some knotes as infux. This could lead to the deadlock.
  
  Before kqueue_scan() sleeps, wakeup the threads that are waiting for the
  influx knotes produced by this thread.
