> To test I created a queue on the C++ broker with a size limit of 512 bytes, 
> and a policy of "ring"
> First I sent 5 messages each of size 100 bytes.
> Then I sent a 6th 100 byte message - as expected this dequeued one of the 
> existing messages
> next I sent a single message of size 400 bytes
> This caused only a single existing message to be dequeued, leading to 5 
> messages being enqueued with a total depth of 900 bytes (as reported by 
> qpid-tool).  At this point I would have expected all but one of the existing 
> messages to have been dequeued in order to make room for the 400 byte message
> Finally I sent a single 1000 byte message.  This message in itself should 
> have been too big for the queue, however it was enqueued; and only one 100 
> byte message was dequeued - leaving a total byte depth of 1800 bytes being 
> enqueued.
