lang/rust runs as many processes in parallel as it wants during the build, not respecting the disabled "ALLOW_MAKE_JOBS" in Poudriere.
Specifically, there are some rustc's run by cargo.

This seems to work, but I'm not sure.
rustc running alone still eats up all cpus!

No, it doesn't help at all.

Can you try OpenBSD fix? Someone should bisect and report it upstream, so the downstream patch is transient rather than a maintenance burden.
Thank you, I will try it next time I'm updating.
Suggested patch has more or less been applied upstream. Given no further
feedback I'm assuming this is no longer a problem.
