Had me worried there for a while though.

Excceptions make me nervous.

FWIW. I think the ping() based implementation is probably the best one
to go for, because it doesn't raise any exceptions (so say the MySQL[db]
docs, anyway), and it automagically reconnects internally to MySQL's own
code if it can. No point in making work for ourselves, eh? ;-)

Although, importing the MySQLdb errorcodes is a good idea, and perhaps
I'll make use of them in a future version.

All of which reminds me, must document the fact that if you change the
MySQL connection details, (I think) you need to restart Mailman.

Anyways, thanks for the responses.

If you're not totally appauled by the code quality, and you think it'll
work, let me know, and (if necessary) I'll upload it to the sourceforge
site patches section, from which you may apply a GPL license to it (as
far as I'm concerned, and I think it's safe from the perspective of the
related software, etc.), and do what you wish with it, as long as it's
appropriately credited, and, for preference continues to include a link
to http://www.orenet.co.uk/ in it.
