      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.

      If no-one feels up to it, I'd still appreciate some hints and I could try to fix it myself. 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.
