/** Internal class LCount is used to track the number of
listeners registered for a given event name, as an entry
in a global hashtable. This should allow us to avoid generating,
or discard, 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.
???? CONCERN: Hashtables are known to be "overserialized" in
current versions of Java. That may impact performance.
???? CONCERN: The hashtable should probably be a per-document object.
Finer granularity would be even better, but would cost more cycles to
resolve and might not save enough event traffic to be worth the investment.
