Since that *still* wouldn't fix the problem with the whole "count
elevated by other things" issue, I really don't want to hear about
these random broken hacks that are fundamentally broken crap.

Really. Stop cc'ing me with "let's implement this hack that cannot
work in general". I'm not interested. There's a reason we don't do
this. We don't make up random hacks that we know cannot work in the
general case.
