The patch looks okay.  I have ideas about improving the name, but that can wait.

What I think is still needed is an actual use case with performance numbers.

My wish would be a more generic "garbage collection" mechanism that
would collect stale cache entries and get rid of them in the
background.  Doing that synchronously doesn't really make sense, IMO.

But that can be done independently of this patch, obviously.
