Yes, but that doesn't help across requests (e.g., request A reads session > 
request B reads session > request A updates session > request B overwrites 
request A's update). The session table in the db does include a "locked" 
field, but as far as I can tell, it is not actually used. Another option 
would be to do a select-for-update, which would result in the db locking 
the record until the transaction completes (though in the case of SQLite, I 
think the whole db gets locked).
