33  * WARNING - Great care should be taken when receiving events of this type.
34  * They are sent from within the Wrapper's internal timing thread. If the
35  * listner takes too much time working with the event, Wrapper performance
36  * could be adversely affected. If unsure, it is recommended that events
37  * of this type not be included.
