Last time I looked, zope was explicitely requiring Python 2.1.x.
This is the most popular Python application, so I've let myself
guided by this.
We can add a 22-pth version too, if needed. I had to use some
unusual hacks to get coexistence with plain python21 (setting
the version string to "2p1.3" instead "2.1.3" because many
add-on packages use the first 3 characters of it to find modules
to load), but if it works for 2.1 it should do for 2.2 as well.

Have you tried running the Python selftests? 21-pth dumps
core on test-poll.py with some obscure pth message:
**Pth** SCHEDULER INTERNAL ERROR: no more thread(s) available to schedule!?!?
