With recent pkg fallout, I'm trying to build rust myself first time ever (as far as I can remember), and it's failing running out of swap on the following step:

Here I pressed ^C as the build actually continues despite several rustdoc, python, and other processes being killed.

swap_pager: out of swap space
swp_pager_getswapspace(20): failed
swap_pager: out of swap space
swp_pager_getswapspace(11): failed

The system has 32G of RAM and 2GB swap partition (as advised by zfs-auto installation option), top shows about 28G of memory free at that moment, so I'm wondering why the swap is being used, and if 2G should be enough to build rust.

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.
