I object to any sort that claims to be more stable than its author.
Speaking of which, by giving up the so-called stability of 2.3's
list.sort(), I can speed sorting of exponentially distributed random floats
by nearly 0.017%!  That's almost a fiftieth of a percent.  Some of the
floats in the result are smaller than their left neighbor, but that's only
because I had to mutate some of the values, and they're not a lot smaller
