 * <p>
 * The presence of a "throws TooManyListenersException" clause on any given
 * concrete implementation of the normally multicast "void addXyzEventListener"
 * event listener registration pattern is used to annotate that interface as
 * implementing a unicast Listener special case, that is, that one and only

 * concurrently.
