Also. I forgot that the kernel always resets ->exit_signal to SIGCHLD on
exec or reparenting. Reparenting is probably fine. But what about exec?
Should it keep ->exit_signal == 0 if "autoreap" ? I think it should not, to
avoid the strange special case.

Not delivering any signal was the objective of this patch series, so yes 
exit_signal == 0 should survive an exec and even re-exec.
