No, but you should be using Python 2.2.1 (it's got bugfixes over 2.2 that
are important for Zope).

Yes, Python CVS does.

No, not obvious.  Python 2.2.1 doesn't have a Boolean type, but does have
the names True and False in the builtin namespace (bound to 1 and 0,
respectively).  For things like

>         prepare_ok = True
>         for r in txn._resources:
>             if prepare_ok and not r.prepare(txn):
>                 prepare_ok = False

that's probably clearer than, say

    prepare_ok = [42]
and
    prepare_ok = `[42]`[:0]

as ways of spelling true and false <wink>.
