Yeah, I keep making that mistake, because I always confuse this with
the exit_signal handling.

Just mentally kick me next time I do that: "Christ, Linus, not
*again*! Take your damn meds"

Anyway, it's more the "another confusing and fragile special case that
will probably not be used very widely and cause confusion because it
lacks any test coverage" thing I worry about most.
