Saw another TestScript flake on OpenBSD. Might be unrelated but they are both generic enough that I think we can start by tracking them together.

I'm not sure where that first failure came from, but the second looks like #35045, which makes me suspect some lingering netpoll breakage (CC @ianlancetaylor).

I can't figure out what sources were used for the openbsd failure. The log says openbsd-amd64-64 at e4992e62bd450927e94469a0422c516d45599c7f but I don't see a commit with that hash in the Go repo.

(In particular I'm wondering whether that build included https://golang.org/cl/204937 == 04e80fb).

No idea what is going on here, and no occurrences in the builder logs. I'm going to assume this was due to the runtime instability we had.
