Those kind of hacks should not be needed if Barry puts his own
email package inside the Mailman package. All local imports
will pick up his version automatically; even though I'd suggest 
to use explicit imports for it in the Mailman code to avoid magical
problems ;-)

Hacking __path__ should really only be the last resort... it
(usually) breaks installers, gives importers a hard time, 
etc. 

We should not consider this good practice even though it
may be needed sometimes (e.g. by PyXML).
