Depending on the test configuration parameters, it was possible to get an OutOfMemory error. The causes were:

- The MessageList was holding on to all the messages being consumed, changed this so that it only holds on to the messageIds
 - Was using a non persistent broker, but was sending it persistent messages, in the topic case, he holds on to the messages in a memory based message store.  By default we now send non persistent messages.
