So much for my estimating skills. I was only off by 1 beta and 6 weeks.
I just checked in the code to close this issue
(http://bugs.python.org/issue3038). It's in both 2.6 and 3.0.
I've added test cases, but if anyone has any other uses for this, please
look at it and let me know if you have any problems.
