The case of the programs that were launched with impossible command line options
Oh that’s a known problem. There are many patch sets floating around that fix it by triggering the OOM killer when the system is thrashing: https://github.com/hakavlad/le9-patch
I’ve never ran into this specific problem back when I was daily driving desktop Linux, but I did run into 1000 similar ones that needed bandaid solutions. It’s death of a thousand cuts: https://news.ycombinator.com/item?id=28490753

Help me out here, why does Windows 10 handle my low memory situation better than Linux (so far)? How do I fix it?
I actually do use the Zen kernel already. If you are already using the zen kernel , make sure to use the latest one which has le9 patches , imho this patch can Improve user experience in tight memory situations. Check this https://github.com/hakavlad/le9-patch, saw many people praise this , but ymmv. Best of luck

Moving Google Toward the Mainline
- Limit the amount of thrashing or protect some pages from being reclaimed. This has been proposed by Google first and several other people since then, but AFAIK it has never been implemented in the mainline kernel.
Regarding the latter solution, there is a patchset called le9-patch[1] that is included in some alternative Linux kernels and it should be relatively safe to use.
