This would require a much smarter init, and that a child be nice, cooperate and pass on what is requested of it if it's nested children are to be killed. If a child decided to be mean and ignore its parent's requests, the parent can always just kill the child.
(Read the last sentence, and in case you're wondering, no I don't have any children in real life)
