let's rather do:

  if (force)
    lstenersArrived();
  else
    InspectorTest.addSniffer(Components.EventListenersView.prototype,
"_eventListenersArrivedForTest", listenersArrived);

Because someone else might be sniffing the _eventListenersArrivedForTest
somewhere..

Went back and forth and that actually, good point
