Why do you persist in believing this? I sent timing results of doing a
setlocale for every record here about a year ago. Sorting on the pg_strxfrm I
posted (and Conway rewrote) was about twice as slow as sorting without using
it. So it's slow but not spectacularly awful.

This depends on having a good setlocale implementation, but glibc at least
seems to be satisfactory.
