Yes. It sounds like he Rick slowed down fork enough the system didn't fall
over. There may be some other policy changes as well. But my hunch is that
it is a fork speed thing. If all that happens is that the system hits
OOM when subjected to an unreasonable load I don't see this as a problem.

The truly interesting question is what happens when you and more swap.
With sufficient swap will it work?
