Comment(by bonefish):

 I noticed that too. I don't think anything has changed that directly
 influences the page handling in low memory situations. My guess is that
 the lowered lock contention in the VM leads to odd quasi livelock
 situations where threads keep stealing each others pages, in the end
 making virtually no progress anymore. The whole mechanism needs reworking
 I'm afraid.
