title: how to automatically restart a node server?
body: <p>We are finishing development of a project, the client is already using it but occasionally some errors occur - crashing the server.</p>
  
  <p>I know I could register a service as 'upstart' script on linux, in order to have my node service restart when it crashes. </p>
  
  <p>But our server is running other stuff, so we can't restart it. 
  Well, actually, while writing, I realize I have two questions then:</p>
  
  <ul>
  <li>Will 'upstart' work without having to reboot? Something is just whispering yes to me :)</li>
  <li>If not, what other option would I have to 'respawn' my node server when it crashes?</li>
  </ul>
