// creation and deletion of the streams. This implentation includes a gross hack
// in which the HTTP/2 weight is set to a transformation of the
// spdy::SpdyPriority value in order to support servers which do not honor
// HTTP/2 stream dependencies and instead treat the weight value like a SPDY/3
// priority.
// TODO(rch): Eliminate this gross hack when servers no longer act like this.
