If a session can't be created in memcached, it needs to be created in a
more permanent store like a database or a disk. Almost any usage that
puts the cache in the critical path is incorrect; memcached is a cache,
not a data store replacement.

This is what I was referring to. I noticed this and several other
problems when I first moved the Facebook infrastructure to memcached. I
started writing patches, but didn't have time to get them to a usable
state, so I'm glad to see Steven et al ended up doing this.
