Sending the message to be rolled back to the head of the queue will
add a delay (since consumers will have to process all pending messages
first).

If you want an explicit delay before republishing the message I'd
suggest using Camel with the delayer...
http://activemq.apache.org/camel/delayer.html

so you'd send to the delay queue with some timeout; then the delayer
could then route it back to the queue
