   > Probably it would even be better to use the method at #2211 so that we can precisely control the redelivery.
   
   We need both  _redeliverUnacknowledgedMessages()_ and #2211. The latter could be used for failed messages but we'd still need to keep track of the number of times it failed and a delay to apply. This won't help for messages which were being processed when the JVM died, which is why we need _redeliverUnacknowledgedMessages()_ at init time.

   I'm confused. Do you mean that this is what it does even without using _redeliverUnacknowledgedMessages_?
