title: Is it safe to reuse a conduit?
body: <p>Is it safe to perform multiple actions using the same conduit value? Something like</p>
  
  <pre><code>do
    let sink = sinkSocket sock
  
    something $$ sink
    somethingElse $$ sink
  </code></pre>
  
  <p>I recall that in the early versions of conduit there were some dirty hacks that made this unsafe. What's the current status?</p>
  
  <p>(Note that <code>sinkSocket</code> doesn't close the socket.)</p>
