I think I mis-interpret Andrei's slides. I think what he meant to sort
a chain of slices is such that to move the smaller elements into the
first-given slices in-place, thus moving items around whatever lists
underlying those slices.

And for zip, I think he meant sort the first slice, but moving in-
place the items referred by the others in lock-step.
