We have a cache with a DB for a backing store. The cache has a write-behind delay of about 10 seconds.

We see an error when we:

- Write new object to the cache
- Remove object from cache before it gets written to cachestore (because we're still within the 10 secs and the object has not made it to the db yet).

At first i was thinking "coherence should know if the object is in the db or not, and do the right thing", but i guess that's not the case?
