The OOM killer has almost never worked for me. I think once or twice only, the rest of the time, high memory pressure combined with high storage pressure effectively locks up the system. Easiest way to trigger it is to start eclipse, virtual box and start a system update (just package download, not install) and I can't move my mouse any more.
