Hi Jon,

Sorry for the slow reply.

You're deadlocking here because you're in the main loop thread already.
You need to get out of that thread - if you use our QueueingConsumer class
rather than DefaultConsumer and then call nextDelivery() from your own
thread you will pick up the next message in your own thread and then find
that you can make subsequent calls back to Rabbit.

I hope that makes some sense.
