I tried this with the exception that my ports were 28090 and 28091 and I
changed filenames to suit my machine.  (I already use port 8090 for
something else.)  The runzeo process started fine and told me what it was
doing up until I killed it:

    2006-05-08T00:11:59 (11371) opening storage '1' using FileStorage
    2006-05-08T00:12:02 (11371) StorageServer created RW with storages: 1:RW:/Users/skip/hammie.db

    2006-05-08T00:14:52 (11371) closing storage '1'

While it was running, I tried running sb_filter.py.  It just hung.  When I
got tired and killed it, it emitted this traceback:

Is there something magical about ports 8090 and 8091?
