Given how Go has no issue being prescriptive as hell on other things, I don't see why they couldn't just go "set vm. overcommit_memory to 1 and fuck off", that's exactly what e.g. Redis tells you.

Because that is very OS specific.

AFAIK BSDs don't have a concept of overcommit because you can't even turn it off.

And again it would hardly be the first time Go makes OS-specific decisions.
