I am adding keystone because it has some logic for cache invalidation across projects. Also, we ran into this issue originally on keystone.
The code on https://github.com/openstack/keystone/blob/stable/mitaka/keystone/common/cache/core.py#L71 is supposed to proxy calls to cache invalidation. Unfortunately, lines 123 and 124 do not set setters and deleters to _hard_invalidated and _soft_invalidated. This leads to dogpile.cache working like it was not patched. ** Also affects: keystone Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!

So this invalidation works for particular region object only. If there is a need to invalidate a region so that values in it are no more valid for other instances of CacheRegion (either in the same process or in another one) - it's simply impossible.
