Or we could provide a patch for Python 2.2.1?  It looks like it's a
two-liner.

It also depends on what the PBF's plans are for their Python-in-a-tie
release (based on the 2.2 CVS branch).  If they're planning to do it
soon, we can wait for that; otherwise, we may have to do a 2.2.2
release sooner.
