the rehashing process.
Can't we register an *async* notification listener on ViewChanged ?
You'd still have a *lot* of notifications being queued up for the notification
executor since you will have 1 event *per entry* that is moved. Could be thousands, tens
of thousands in cases. All other notifications will be severely delayed (depending on
your async notifier executor threadpool size)
