> There are several ways by which an HTTP/2 stream can be closed. Due to the built-in asynchronous behavior, and to avoid unnecessary churn when a request is cancelled/aborted there are two places where the boolean stream's state closed can be set to true: cancelImpl and close. The current code completes the subscriber in cancelImpl, but the subscriber should also be completed in close. The intermittent failure happens if close gets ever called before cancelImpl.
