Fantastic!

I think what would be interesting would be adding a _ton_ of prints to that
function, basically at every step, and comparing to the old version (which
unfortunately was in a somewhat different place, but look at the diff and it
should be apparent). Reading over the code, the computations should be
identical, but perhaps there's a subtle bug somewhere, or the inputs end up
different.

If you're not up to figuring out how to do this yourself, I can try to write up
some patches to apply to the old + new versions.
