I'm making TestTransportAndServerSharedBodyRace_h2 skip for now, but it's failing. Sometimes it requires a few runs:

$ go test -v -run=TestTransportAndServerSharedBodyRace -count=20
=== RUN   TestTransportAndServerSharedBodyRace_h1
--- PASS: TestTransportAndServerSharedBodyRace_h1 (0.50s)
=== RUN   TestTransportAndServerSharedBodyRace_h2
--- PASS: TestTransportAndServerSharedBodyRace_h2 (0.04s)
=== RUN   TestTransportAndServerSharedBodyRace_h1
--- PASS: TestTransportAndServerSharedBodyRace_h1 (0.50s)
=== RUN   TestTransportAndServerSharedBodyRace_h2

Fix: https://golang.org/cl/18288 (and then need to bundle it into std)

bradfitz added a commit to golang/net that referenced this issue Jan 7, 2016
The Transport code wasn't always sending a RST_STREAM to the server
in a few cases, and was also forgetting to flush its buffer.

I believe each part of this change was part of making golang/go#13556
not flaky. No additional tests at the moment;
TestTransportAndServerSharedBodyRace_h2 is pretty comprehensive as-is,
at least for an integration test. I should probably add some
finer-grained tests in the future.

Updates golang/go#13556
