title: How to make uwsgi --emperor run as daemon
body: <p>I'm using yaml. It has a line says : <code>daemonize : /var/www/apps/myapp.log</code></p>
  
  <p>If <code>uwsgi -y vassals/myappconfig.yaml</code>, the website runs in background. I can do other things in terminal, even logout. This is the effect I'm expecting.</p>
  
  <p>If <code>uwsgi --emperor vassals</code>, the website can run, but it stuck up in terminal. I must use <code>ctrl + c</code> to end it to return to terminal. Then the website is down. That's not what I'm expecting.</p>
  
  <p>I don't want to use things like <code>nohup</code>. If <code>uwsgi --emperor</code> is not the right solution, I'd rather to load websites one by one, all run daemonized.</p>
