Hi All, I'm guessing the answer to this one is "use glibc", but I can't find any existing commentary on this in within the go ecosystem and thought it was worth a quick shot in case there is a fix. I'm aware that tsan and glibc are fairly well intermingled, so probably requires a lot of work possibly on both musl and go's part.
Just in case there is a quick fix though, here's a minimal reproduce using docker. I'd be interested in seeing this one work some day.
