> While testing AMQ 4.2 SNAPSHOT from 3/9, I can create the situation wherein a consumer
that was killed and then restarted will get the "prefetchLimit" # of messages last, which
means they are out of order.
> setup:
> 1 Broker
> Consumer on Durable topic, prefetchSize=20
> Publisher publishes to Durable topic
> Let some messages flow, then kill off Consumer.  Let a few thousand messages queue up,
then restart the consumer.
> The Broker begins redelivery of messages, and then when it gets down to the end of the
queue, the very first 20 messages from when the Consumer first went down are delivered.  This
means that those messages come out of order.
