    Yeah, it's not wonderfully pretty, but at least this patch makes bugs
    _less_ likely, by having more of the common stuff abstracted out. And
    clearly allow_signal() was broken before, since it didn't allow anything
    but deadly signals, despite the fact that it was supposed to be generic.
