   Anyway - to enforce this, we actually don't give instances access to SVN.  If
   anything is missing from datastore, it'll be a 404. If the cronjobs don't
   manage to catch everything - uhoh. On the other hand, we'll figure it out
   pretty soon, and it also means that legitimate 404s are caught before a round
   trip to SVN.
