Request streaming test sometimes fails: HTTP/2 stream not closed cleanly

[csvance]

I'm not sure if this is an issue with us overloading the test server or something on the client side, but it should be documented here.

Looks like its the server, my guess is we are overloading it (500k messages/sec).
