Implement slow consumers flag
-----------------------------

                 Key: JBMESSAGING-1072
                 URL: http://jira.jboss.com/jira/browse/JBMESSAGING-1072
             Project: JBoss Messaging
          Issue Type: Task
            Reporter: Tim Fox
         Assigned To: Tim Fox
             Fix For: 1.4.0.GA


If there are slow and fast consumer(s)  consuming from the same queue, then load balancing might not work as one would expect.

By default, each consumer has a prefetch size which determines how many messages it would accept before accepting any more.

So if you send 100 messages, then 50 might go to the slow consumer then the other 50 the fast consumer.

The slow consumer woud then take a long time to process the 50 messages, resulting in non optimal processing time.
