Hi;

I am CC'ing Andrey Chernov as he has done changes in qsort(3).

The change is interesting, but it has to be benchmarked first. Perhaps you can
try the tests in lib/libc/tests/stdlib/ and see how the compare to the existing
code?
FWIW, ministat(1) is welcome too ;).

Also, we generally don't touch the stuff in contrib until the changes are
reviewed by upstream maintainers.
