Changeset 2f14616 for fedd/federation

Message:

Multi info was all screwed up if the requester wasn't authorized to see any one
of the experiments. This gracefully handles the exceptions that
check_experiment_access throws as well as making some threading.Locks
threading.RLocks to head off the coming deadlocks.
