@etchedpixels@mastodon.social ...given that i can still experimentally replicate that behaviour on modern kernels... that behaviour is still present. to my knowledge, the kernel still makes a great effort to avoid OOM killing processes until it's well and truly screwed, thus in a situation where memory is nearly 100% filled with anonymous pages, you will inevitably end up thrashing file pages.
