:-) Or, seen another way, "yes". It's a start. It'd work for when
non-persistent messages were being sent through the broker. We already
have experimental code doing most of this, similar I suppose to the code
you have -- but it's not ready even for experimentation at the moment.

The full solution needs to carefully balance three interacting components:

 - persistent storage of messages
 - the memory needs of the queue-data-structure of messages in each
   AMQP-queue
 - TX-class transactions
