 sophisticated control over when and how events are processed. Applications
 which implement multi-session servers or which implement their own
 internal event queueing will probably be the major clients of these

 disposing of the AppleEvent when the handler returns. They can be used to
 asynchronously process the event (as MacApp does).

 attempt to redispatch the event. Several constants for the dispatcher
 parameter allow special behavior. They are:
