title: make a jupyter notebook run even if the page is closed
body: <p>I love notebooks. I love them so much that I have many of them running at the same time, often in different browsers, sometimes on different remote clients. I miss one feature: when I close the tab corresponding to a running notebook, it warns that the corresponding run will be stopped.</p>
  
  <p>My question:</p>
  
  <blockquote>
    <p>How do I make a jupyter notebook resume it's run even if the page is closed ?</p>
  </blockquote>
  
  <p>such that I can:</p>
  
  <ul>
  <li>re-open the tab in another browser (possibly on a remote computer such as a tablet),</li>
  <li>restart a browser when it needs to,</li>
  <li>close those with long running time for later inspection.</li>
  </ul>
  
  <p>From what I understand, the client-server architecture could make that possible, but that there may be issues with multiple concurrent runs... </p>
  
  <p>PS: I created an issue on <a href="https://github.com/jupyter/notebook/issues/2446" rel="nofollow noreferrer">GitHub</a></p>
