   * With regular request bodies it is not legal to write bytes to the sink passed to
   * [RequestBody.writeTo] after that method returns. For duplex requests bodies that condition is
   * lifted. Such writes occur on an application-provided thread and may occur concurrently with
   * reads of the [ResponseBody]. For duplex request bodies, [writeTo] should return

   * The initial write to delegateRef is made definitely visible via the semantics of

   * however that is fine since the correctness is based on the atomic state in our base class. The
