FWIW there's no real need using a separate thread to create a consumer
in it if you are using the MessageListener (async) approach. You only
need to create separate threads if you are using the sync approach
(consumer.receive*() stuff).

Subscribing to messages lasts forever; so there is no explicit
graceful shutdown. Maybe expose an MBean so folks can explicitly close
things down - or listen to some queue/topic so folks can send your
process a message to close down gracefully?
