Comment (by isis):

 This worked quite well, with one minor glitch:

 From BridgeDB's log files:

 It's ''probably'' just an issue with one of the old hashring classes in
 `bridgedb.Bridges` having a stupid/buggy `__len__()` method that double-
 counts bridges which are in a hashring and also in one of that hashring's
 sub-hashrings.
