Zero's patch looks good to me, but it may be a couple of days before I can get to applying it. If anyone else can handle it before then, please feel free :)

Also, Zero, if you could review and sign the contributor agreement, that would be great: http://www.python.org/psf/contrib/contrib-form/ (while this patch is mechanical enough to be OK without one, it's still good to take care of the formalities of granting the PSF clear redistribution rights for CPython contributions)
