Ah... so then calling serve_forever() won't block?

My current code, which illustrates what I'm attempting can be found
here - http://www.rafb.net/paste/results/oIqI3Q11.html

Basically, the server isn't the main focus, what I'm aiming for looks
similar to this

server-----Queue--data_cruncher--MySQLconnection
server---/ /
server-/ /
server -/

So basically having data_cruncher to crunch whatever data there is in
the queue and send it off to the database is the priority. I'm having
trouble with SocketServer, need to do some more experimenting, so I'll
get back to it.
