Return an "interesting" boolean from the event handler function on GFileMonitorSource. An event was "interesting" if it will result in a signal actually being dispatched to the user. It is "uninteresting" if it only hit an already-dirty rate limiter. We will use this information to do some backing off in the backends when faced with a flood of uninteresting events.
