True, although in theory, it works also if you mark them as stable. I've
been running python-2.3 on a stable box without any problems. YMMV.

That is rather suprising. I could only explain that by predicting that
btdownloadheadless doesn't use any unicode objects at all. As I said
before, I think the real test case would be XML parsing.

But hopefully this weekend I could formulate some tests to run to get
something more "scientific". But it might be that my initial
observations were off.

Zope is a special case because it is not supported if you run it on
anything about 2.1. I'm not too familiar with Zope, so maybe some others
can chime in. As for packages that don't work with 2.3, that needs to be
fixed. There is a bug open now that people can report apps that don't
work with 2.3 either because 2.2 is hardcoded or they just need to be
patched.
