Performance Issues with Threaded Python Network Server

[kacper]

PS I forgot one thing - my mom wanted some help with her computer and I was
just acting too quickly; the NEWGROUPS handling in the backend doesn't seem
to care about the timestamp, so it looks like it always returns all the
groups.

PS2 and excuse me about not keeping to the subject - I always mind the rule
of having the code work first, and then optimizing it :-)
