Looks like I got this wrong, adding a file-backed swap space I was actually able to run top, and seeing only 100M of memory being "Free", ~20G memory reported as "Active", and swap usage constantly growing being consumed by rustdoc process; something is really wrong here. > Tried building both as root and user, DISABLE_MAKE_JOBS has no effect.
