Description of problem:
As you add and remove replicated queues within an HA broker, bridges are opened and closed for each queue.  Closing a bridge immediately re-adds the associated channel number into an available pool.  As a result, when the old bridge (channel X) is closed it sends a "detach" command to the broker and the new bridge (assigned the same channel X) sends an "attach" command.  The broker will eventually respond with a "detached" command which was meant for the original bridge on channel X.  Unfortunately, the new bridge on channel X handles this detached command from the broker and flags the bridge as detached.  This process can then repeat for several cycles until it break out of the detach/attach/detached race.

In addition to the detach/attach/detached race, the immediate re-use of channel numbers appears to create other issues like the following:

Version-Release number of selected component (if applicable):
Qpid 0.18-6

How reproducible:
Frequently

Steps to Reproduce:
1. Rapidly create and delete replicated queues
  
Actual results:
Detach/attach/detached loops and other channel errors are seen in the logs.  This issue stops HA replication which stops message flow through the broker.

Expected results:
Channel errors are not encountered
