@bgamari this should be ready for review now that CI cleared it.

Hmm, I was under the impression that getExecutablePath couldn't be robustly implemented on OpenBSD? I suppose I'm mistaken?

It's not implemented via any special kernel magic. This simply falls back to using argv[0] which is good enough in some cases, namely it suffices to fix the problem in #18173 (closed).

Alright, I suppose that is fine.
