	// Unfortunately it doesn't look like it's possible to make use of
	// StateActive to implement graceful shutdown, since StateActive is set
	// after a complete request has been read off the wire with an intent to
	// process it. If we were to race a graceful shutdown against a
	// connection that was just read off the wire (but not yet in
	// StateActive), we would accidentally close the connection out from
	// underneath an active request.
	//
	// We already needed to work around this for Go 1.2 by shimming out a
	// full net.Conn object, so we can just fall back to the old behavior
	// there.
	//
	// I started a golang-nuts thread about this here:
	// https://groups.google.com/forum/#!topic/golang-nuts/Xi8yjBGWfCQ
	// I'd be very eager to find a better way to do this, so reach out to me
	// if you have any ideas.
