-/* NOTE: The old method of idle event handling added the handler using the
-    [NSRunLoop -performSelector:target:argument:order:modes] which caused
-    the invocation to occur at the begining of [NSApplication
-    -nextEventMatchingMask:untilDate:expiration:inMode:dequeue:].  However,
-    the code would be scheduled for invocation with every iteration of
-    the event loop.  This new method simply overrides the method.  The
-    same caveats apply.  In particular, by the time the event loop has
-    called this method, it usually expects to receive an event.  If you
-    plan on stopping the event loop, it is wise to send an event through
-    the queue to ensure this method will return.
-    See wxEventLoop::Exit() for more information.
-
-    This overridden method calls the superclass method with an untilDate
-    parameter that indicates nil should be returned if there are no pending
-    events.  That is, nextEventMatchingMask: should not wait for an event.
-    If nil is returned then idle event processing occurs until the user
-    does not request anymore idle events or until a real event comes through.
-
-    RN: Even though Apple documentation states that nil can be passed in place
-    of [NSDate distantPast] in the untilDate parameter, this causes Jaguar (10.2)
-    to get stuck in some kind of loop deep within nextEventMatchingMask:, thus we
-    need to explicitly pass [NSDate distantPast] instead.
