the kernel assumes on some places that a process _always_ has a parent. So
it can always blindly dereference p->p_pptr. So if we kill init, we will
immediatelly have a nasty set of oopses. It's also a matter of how mildly
Linux/hardware bugs escalate when we get an oops. (if a very rare oops
happens to hit init, the system dies horribly with a storm of oopses,
possibly making the identification of the former oops harder)
