> Description of problem:
> If a message expires in a queue before the HA replicator is able to browse the message,
the message will be skipped and not replicated.  This results in the expired message's async
completion never being finalized which can stall the original source of the expired message
since it will never receive a completion.

message from 'QueueXyz'
> Version-Release number of selected component (if applicable):
> Qpid 0.18
> How reproducible:
> Frequently
> Steps to Reproduce:
> 1. It's a race condition between a message expiring in the queue and the HA browsing
subscription being able to replicate it.
>   
> Actual results:
> The expired message is skipped and its async completion is never finalized.
> Expected results:
> While it is not truly necessary for the HA replicating subscription to replicate an expired
message, the async completion needs to be finished.
