I'm not convinced that removing the item from cache when we get a hit on
everything in the key except for Mesa version is the right way to go.  I
think we should just be hashing the Mesa version in the key so that we
don't hit on mismatched versions.  Then we wouldn't thrash our cache
when we're, say, checking out around different versions of Mesa and
re-pigliting things.
