> When testing consuming messages via NO_ACK the broker continually OOMEd. Switching to
AUTO_ACK cleared things up.
> Looks like that the broker, while dequeing NO_ACK msgs is not allowing them to be gc'd.
May be due to the way the Queue and the PDQ interact. Messages were being sent to a Topic
and consumed by a two clients. 
> Running two sustained.TestClient 
>  - Producer
>  - Consumer
> and a sustained.TestCoordinator  with -DackMode=257 (for no_ack) should cause the broker
to fail fairly quickly.
> More docs on this test can be found on the wiki: http://cwiki.apache.org/qpid/sustained-tests.html
