Code review comment for lp:~cbehrens/nova/lp803165

This looks pretty straight-forward...and not something we can currently unit test. I'm going to run some tests against this branch, but I have one question:

"Exclusive queues may only be consumed from by the current connection"

Is this going to be hindered by using connection pools or reconnecting after a rabbitmq service interruption? The wording is just specific enough to cause me to think about some disaster scenarios. Like, are we going to have to restart every service if rabbitmq goes down to establish new exclusive queues?
