> When a message is redelivered the consumer blocks for the amount of time specified by
the redelivery delay. For a high load scenario where message order is irrelevant this is just
reducing performance and will result in a complete halt if the delay is long and several bad
messages are consumed in a short time. 
> I think what I basically wish for is how it worked in versions 3.x, prior to fix for
AMQ-268. So I would very much like to have configurable option to NOT block consumers when
redelivering messages.

Looking at ActiveMQMessageConsumer.rollback(), I was thinking something in the lines of just
scheduling a task to put the message back on queue after a delay - if configured to, instead
of stopping delivery and a schedule a task to resume delivery again. But I do not possess
an understanding of AMQ thorough enough to predict potential side effects of this, so any
analysis would be helpful.
