Why the hell -9?

TERM is -15 and HUP is -1 (but I would stick to the names).

Using -9 is almost always the wrong answer. It's a last resort when
everything else failed, and it should be reserved for such.

One should never use this command on a day-to-day basis, much less
teach it or suggest it in a mailing list like this one.
