It would be hard to use this because, in addition to the fact that
this is specific to a very particular type of hardware, it only works
if you're trying to do a very particular type of sort. For example,
it wouldn't handle multi-byte characters properly. And it wouldn't
handle integers properly either - you'd end up sorting negatives after
positives. You could possibly still find applications for it but
they'd be quite narrow, I think.
