asyncore, asynchat and threads

[Joshua Moore-Oliva]

Well, I took at look at twisted..  and it seems pretty scary ;)

What I've done though is made some very minor changes to asyncore and asynchat, and now it appears to be threadsafe//more controllable.

If all works out well for me I'll submit the patch to python, since it's fully backwards compatbile with the old behaviour.

Thanks for the help
