ImportSession doesnt seem to actually import the session data if using native php session support. Furthermore, in that case it seems to delete the existing session, changing the users tokens (which can be annoying)
Given we already have to store request info to make this scheme work, im not sure why we don't just store this info in the db (or even just in memcache if something more ephemeral is wanted.)
