I see nothing suspicious or racy in the test.

I'm afraid I won't be able to help on this one, just like I was unable to help last time in #14061.

I run

go test -v -short -run=TestServerKeepAlivesEnabled_h2 net/http

in a loop against https://go-review.googlesource.com/#/c/35352/2 on my both windows xp and windows 7. It didn't fail even once.

Err, I just noticed this was supposed to be a windows issue, and that the error is not exactly the same. Should I open a separate issue?
