          Issue Type: Task
            Reporter: Tim Fox
         Assigned To: Tim Fox
            Priority: Minor
             Fix For: 2.0.0 Beta 1


The current version of order preservation involves preventing messages being sucked from one queue to another more than once.

This could be improved by encoding the nodeid/counter for each node sucked from in a header.

The counter would be reset every time all consumers are closed on a particular node.

A message won't be sucked to a node if its node id is encoded in the header and the distributor's current counter value matches the value in the header.
