Configuring Non-Blocking Redelivery in the Broker

[Chris Pratt]

Is it possible to configure the new ActiveMQ 5.6 Non-Blocking Redelivery in
the Broker itself?  Or can it only be done in the ConnectionFactory on the
client?  If it is possible, does anyone have a short example of a proper
activemq.xml that might show me how to achieve this?  Thanks.
