The patches that giampaolo sent you were for 2.x, not 3.x .  Arguably
they should be applied to 2.6 first, tested, etc., then be run through
the 2.6 to 3.0 converter, then adjusted for str/bytes stuff.

One of my concerns with your changes (which are hard to work out because
the diff is so huge, could you attach your actual files?) is that they
seem to change asyncore/asynchat for no other reason than to be different.

The changes that giampaolo sent you (that were from some earlier work
that I did) preserved compatibility while adding better error handling, etc.

But maybe I'm just not reading the diff correctly.
