  Log:
  SVN rev 200652 on 2009-12-17 21:17:13Z by thompsa
  
  If the runcount is non-zero in eventhandler_deregister() then one or more
  threads are executing the eventhandler, sleep in this case to make it safe for
  module unload. If the runcount was up then an entry would have been marked
  EHE_DEAD_PRIORITY so use this as a trigger to do the wakeup in
  eventhandler_prune_list().
