I think we do need. While playing with these patches I noticed that
killall5 sends SIGKILL explicitly to init during shutdown on my system.
Note also http://marc.info/?t=120544648800001

(offtopic: and "PATCH 5/5" helped me to figure out why init wastes CPU
 on my system, it stats /dev/initctl (which I don't have) every 5 secs).
