@whitequark @pmarheine @regehr @dotstdy @tedmielczarek You can definitely limit cgroup memory usage and force just a cgroup to OOM if it collectively runs out (eg, your 16 parallel linkers in a single cgroup). On a systemd based Linux this can be scripted, so you could run a build in an environment where it could only use a maximum of X amount of system RAM, although you'd have to decide the X in advance and if other bits used an unexpected amount of RAM you could still blow up.
