/** Internal class LCount is used to track the number of
    listeners registered for a given event name, as an entry
    in a global Map. This should allow us to avoid generating,
    or discarding, events for which no listeners are registered.

    ***** There should undoubtedly be methods here to manipulate
    this table. At the moment that code's residing in NodeImpl.
    Move it when we have a chance to do so. Sorry; we were
    rushed.
