Of course, you are aware that this decoupling of activities
significantly increases the probability to observe inconsistencies:
* added or modified documents not (yet) found by a catalog search
* real inconsistencies due to restarts/failures
The first example, above, can be tackled by documentation and education.
For the second, cleanup operations that either go back to a previous
consistent state or finish what was on the long lived queue.
Not that easy, I fear.
At least, I calls for a formal project...
