Description
I see a race on the linux-amd64-race trybot running over some unrelated code (CL 32923):
https://storage.googleapis.com/go-build-log/17537d3e/linux-amd64-race_d3fd3644.log
I see that there are some recent test-flake-related commits in net/http but I cannot reproduce the race locally within a few test -race runs so I don't know whether it's fixed or not.
