Running this race over home WiFi shows the Times (`0002`) completes just slightly sooner than the Post (`0001`):

   * ### Duplex Transmission
   *
   * With regular HTTP calls the request always completes sending before the response may begin
   * receiving. With duplex the request and response may be interleaved! That is, request body bytes
   * may be sent after response headers or body bytes have been received.
