#3650 Regression-testing on OpenBSD amd64 is a fork-bomb

[Philipp Klaus Krause]

I've installed OpenBSD 7.3 in an amd64 VM (qemu, Debian GNU/Linux host). Any regression test target other than test-host is a fork-bomb. I see this problem neither when using Debian GNU/Linux on amd64, nor when using OpenBSD on powerpc64.

I cannot reproduce this issue using OpenBSD 7.4.
