One potential downside of db sessions is that you can have race conditions, as the session record does not get locked (unless something has changed). On the plus side, if you have multiple Ajax requests that all just need to read (but not write to) the session, they can be handled simultaneously (with file based sessions, because the session file is locked by each request, multiple Ajax requests must be handled one at a time, which is safer, but also slower).
