Ah, again. :) Rusty Lynch and me tried something similar at leat twice but with no avail.
We had a modular OOM killers infrastructure with two new killers. One would just panic on OOM situation, and other did account for parents which repeatedly spawned 'bad' children. Some people called it 'a bit right winged'. :)
Take a look at http://linux.ursulin.net if you are interested. I did not sync it with the latest kernel since nobody was interested. It worked for me.
