BTW, is there an easy way to via JMX look at the DLQ messages and determine if 
they were sent here due to expiration?  I didn't see any hints when I looked 
that the messages had been expired and thus sent to the DLQ.  Perhaps the 
messages should get a property attached to explain the reason for DLQ delivery? 
 Something like a "dlqDeliveryReason" which could be "expired" or "failure" and 
on "failure" you can go look at "dlqDeliveryFailureCause" for more detail.

Are there any other reasons why a message might be sent to the DLQ?
