In many cases,
Now the resource is in state 2, the cache in state 1, but marked valid.
It would be great if there was some (optional) synchronization between the two cache annotations, that prevents such a race condition, if possible even in multi-node configurations.

We looked at this thoroughly and discussed internally what we could do at the abstraction level.
A general mechanism that would help synchronizing evict and put operations would probably ruin the performance. Besides, I haven't found a cache provider that offers such feature.
Do you guys have concrete proposals on how to implement this efficiently against specific cache providers? In particular, how to reduce the locking to just the specific cache entry as opposed to blocking access to the entire cache region?
