title: How to render a long list in react-relay?
body: <p>A lazy scrolling list component for react-web
  backing onto a Relay Connection, with paginated fetching,
  while offering good performance and memory characteristics.</p>
  
  <p>Two things to manage</p>
  
  <ul>
  <li>Data fetching through providing pagination parameters to query, manipulation of the relay store</li>
  <li>Component rendering, manipulation of the virtual DOM</li>
  </ul>
  
  <p>Is there some particular list component which handles this well?
  Is there an established pattern for implementing this common mechanism? </p>
