What did you do?

~/go/src$ while go test -race net/http -count=1 ; do true; done

What did you expect to see?

Consistently passing tests.

What did you see instead?

Lots of passing tests, followed by an apparent deadlock.

Notably, the goroutine dump shows neither the Server goroutine started by the test nor the serve goroutine that that call would have started for the connection. I don't know what to make of that. 😵‍💫

I got another one of these hammering on go test -race net net/http locally, so this does seem to be platform-independent and reproducible. I have no idea how it is happening, though. 🤔

(It took around 200 runs to reproduce.)

I've been hitting this a bunch in TryBots, and given the failure rate I think it should be bisectable. Trying to git bisect now.
