A simple test to allow profiler to get an idea of how much memory is allocated per

temporary Queue. It appears that the ConsumerAdvisory - one for each Connection, holds
a copy of every temporary Queue in the system.

I don't think this is a big issue - unless - as in this case - all the connections and the
broker are in the same jvm.
