---------------------------------------

Hmmm, this requires some thought since you can chain cache stores. This means that, you could be preloading from a shared cache store but wanting that to be stored in your local cache store. What you want to avoid is to store in the same cache store from which you read. Trustin, fancy looking into this?

> When enabling logging on the CacheStore, which is being used with preload=true, I can clearly see that during the preload operation each value is read from the store and immediately after that stored again.
> This is quite a performance hit in application loading, as the whole store is written again without this being needed.
