> Create a queue and publish one message to it. Then start a consumer (pre-acquiring subscription),
with credit for one message. When the message is delivered, sleep for a short while and start
a new consumer on the same queue. Then have the first consumer release the message.
> The released message is now available for redelivery. Unfortunately the first consumer
is picked as the consumer to be notified of this. That consumers connection then attempts
to deliver the message but finds it has insufficient credit. The second consumer however is
not notified and the broker does not attempt to dispatch the message.
> (This is a bug introduced by the change in r721685  which was intended to fix QPID-1280).
