* for every message.
*

* the store is modified by some other queue onto which it is
* pushed, and then again persisted to the store. These will be
* two separate PersistableMessage instances (since the latter now
* has different content), but need to share the same
* AsyncCompletion (since they refer to the same incoming transfer
