Indeed; you've done the right thing.

There is nothing unusual about what you are trying to do and the tools 
you are using. And your understanding of acks appears correct.

Odds are that the behaviour you are seeing is due to some subtlety in 
the ruby amqp gem. I should think that the gem devs can get to the 
bottom of this very quickly.
