Did you mean to write 2003-12-29 there, or is this really from 1-2 weeks
ago?

That's odd -- I don't see any failures, and the overnight test runner
reports aren't showing these either.  If you're running on a "very fast"
machine, maybe that's relevant.

Also, are you using Python 2.3.3, or some other Python?  I'm using 2.3.3
below.

Sorry, I don't know what this means -- there aren't any tests with that
name, although there are *many* tests with "Pack" in their name, and with
"Undo" in their name, and a fair number with both in their name.

That test I recognize, but it will apparently run for hours on my box
without failing:
