I can't for the life of me find where the article talks about live-lock and the OOM killer. I searched for "lock" and "OOM" and none of them related to that.
He doesn't use the term live-lock, but see "6" at the top of the article where he talks about "pathological behavior at near-OOM". Also "3" "Disabling swap does not prevent disk I/O from becoming a problem". Those, in my experience, have been the situations that I was in that I called live-lock.
