title: when sending multiple redis write commands in pipeline, do I need to read the return values?
body: <p>for example:</p>
  
  <pre><code>344         r.Send("HINCRBY", key, set_timestamp, value)
  345         r.Send("EXPIRE", key, 84600)
  346         r.Flush()
  347         //r.Receive()
  348         //r.Receive()
  </code></pre>
  
  <p>do I need lines 347 and 348 to be uncommented? I don't care about the return values. Is there an advantage to not reading them?</p>
