The broker holds state about unacknowledged messages - and will hold 
that state until either the broker shuts down or the client disappears.
Remember that acknowleding a message will acknowledge all messages 
consumed by the client's Session. Depending on what your doing, you may 
want to use individual acknowledge, which is an ActiveMQ specific feature.
