     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.
