  SVN rev 207439 on 2010-04-30 16:29:05Z by zml
  
  Handle taskqueue_drain(9) correctly on a threaded taskqueue:
  
  taskqueue_drain(9) will not correctly detect whether a task is
  currently running.  The check is against a field in the taskqueue
  struct, but for a threaded queue with more than one thread, multiple
  threads can simultaneously be running a task, thus stomping over the
  tq_running field.
