When something weird happens, it might be better to kill init and have the machine reset itself after the panic (echo 30 > /proc/sys/kernel/panic).
Killing all other things and leaving just init intact makes for a machine which is as good as dead, without a chance for recovery-by-reboot...
OTOH, I haven't heard of the OOM killer ever chosing init, not even of people who tried creating these special kinds of situations to trigger it on purpose.
