Tried this out on latest trunk today - I suspect the real problem was: 
https://issues.apache.org/activemq/browse/AMQ-2475
Looks fixed now

> MemoryUsage stays at 100% used forever after all messages are sent

> We  use a network of brokers and topic to do messaging. All our message 
> producers and consumers talk to the local VM broker. We reply on bridges 
> between network of brokers to move messages between brokers. We found a case 
> that MemoryUsage stays at 100% forever after all messages are sent.
> I attached two files to show this memory leak problem. TryJmsClient keeps 
> sending persistent messages to a Topic. TryJmsManager has a message consumer. 
> Start TryJmsManager first and then start TryJmsClient. After running about 10 
> seconds, TryJmsClient stops sending because of getting "SystemUsage memory 
> limit reached" error. About 24K messages are sent and consumer shows it get 
> all messages. Now examine ActiveMQ MemoryUsage printout of TryJmsClient, 
> MemoryUsage percentage stays at 100% or 99% forever. Producer can never send 
> any more messages.
> Note1: If I slow down sending by adding a sleep, I don't see memory leak 
> immediately. I am not sure for longer running time.
> Note2: If I use Queue instead of Topic, there is no memory leak. 
> Note3: This looks like similar to AMQ-1833 that is fixed in 5.2. But after 
> testing with 5.2 snapshot, I still get the problem.
