Review Comment:
this is going to hold a lock on the consumer while the messages are copied
over.
if you have a bad consumer leaking on acks, this could make things worse to
the broker.
Besides this will hold a lock on the ServerConsumer.
Perhaps I'm being over zealous here... but I have seen cases where using the
console to find what was wrong actually made things worse.
That's my only concern here.
