Io.net.test.test.listen on a port, send bytes, receive bytes flaky timeout #31388

Open

On x86_64-openbsd:

 mq run test std-native-znver5-ReleaseSmall-libc 3018 pass, 61 skip, 1 timeout (3080 total)

I'm fairly certain I've seen this timeout on other operating systems too, but it's quite rare.

Wait, no, I confused the name. That seems to be a different issue.

This one still happens too, just rarely:
