-------------------------------------

Is this problem related to or even the same as AMQ-4356?

> Virtual Topics allow us to do things with pub/sub that we cannot otherwise do with JMS
1.1 spec. However, with durable subs we can "unsubscribe" a consumer telling the broker we
are no longer interested in messages. If we just stop consuming, the queues can fill up.
> With the queue-based impl of VT, we have to wait for the queue to be empty to delete
it... to do that reliably, the producer would have to stop producing? And/or we have to use
some TTL for the messages? Not sure...
