After some thought, this use case is indeed some weird, I'm trying to fix it on our end. So I'm cancelling this pull request. @Mike, Thanks so much for your opinions and patience.

For #22 of dogpile.cache, aims to raise exception when backend fails to release lock and keep track of generated result at the same time.
Refactor
Lock._enter_create.Add
NeedAsyncRegenerationException, which would trigger an async regeneration. It also hold anexisting_valuefor results generated at the moment.Add
LockReleaseException, wraps any exception raised by backend when releasing lock. It also contains results that would be returned if no exception is raised.
