In #49209, we identified particular NetBSD and OpenBSD configurations that produce frequent crashes in Go programs due to suspected upstream kernel bugs. We also identified particular platforms that do not appear to be affected by those bugs (namely, builders running on Intel processors), and the resulting -n2 variants of the builders have been running fairly reliably: they exhibit only a few test flakes that appear to be unrelated to the kernel bugs.

On CL 376334, I got a TryBot failure from an OpenBSD builder that appears to be due to #49209. Given that we have identified the affected platforms, that TryBot failure seems entirely avoidable: we could have simply run the TryBot on an unaffected instance instead.

We should reconfigure the NetBSD and OpenBSD TryBots to avoid the builder configurations with known problems.
