    sys/kern             subr_taskqueue.c 
  Log:
  Implement taskqueue_block() and taskqueue_unblock().  These functions allow
  the owner of a queue to block and unblock execution of the tasks in the
  queue while allowing tasks to continue to be added queue.  Combining this
  with taskqueue_drain() allows a queue to be safely disabled.  The unblock
  function may run (or schedule to run) the queue when it is called, just as
  calling taskqueue_enqueue() would.
