Yes. That's basically how vfork() works.

You could make it a special kind of killable - where you can _only_ kill
it (ie only fatal signals will be serviced), and that would work. I
wouldn't do that until people actually start to complain. It's not a
security issue, as the parent _can_ be killed - you just have to kill the
child first.
