I'm pretty skeptical of these arguments, as they depend on assumptions
that there are no CHECK_FOR_INTERRUPTS calls anywhere in the relevant
code paths outside be-secure.c. Even if that's true today, it doesn't
seem like something to depend on.
However, there's definitely merit in the idea that we shouldn't change
the ProcDie behavior if we don't have to in order to fix the NOTIFY
bug --- especially since I'd like to backpatch this. So if you're
happy with the revised patch, I can go with that one.
