This failure has only been observed on the openbsd-arm64-jsing builder, but the failure mode does not appear to be platform-dependent: I noticed in https://go.dev/cl/370696 that the test appears to be racy and added a comment to that effect.

This test was added in CL 72810 (CC @ianlancetaylor @bradfitz @AudriusButkevicius)
