This comment should be changed, but I failed to make the new one.
Actually, this was one of the reasons why the first patch I sent
didn't touch the first ""p->parent_exec_id = ...".

There is a fat comment in exit_notify(), perhaps we can just add
/* see the comment in exit_notify() */.

But the "good" commenent should also explain that, since we re-use
->real_parent, the child also "inherits" the rights _and_ restrictions
to send ->exit_signal != SIGCHLD.
