Yes, that reminds me of course that those two hosts aren't really a
cluster of identical caches.

This software by definition can't because this is not a cache in the usual
memcache sense, it's an actual data store of sessions and other
information that has no other persistence.

When I've asked about this, the response has been that memcache never
fails, so it's just not an issue. I was, umm, not persuaded by that
argument.
