title: django running mutliple sites in development
body: <p>Am currently developing a website that consists of mutliple sites in the same project therefore I have several settings.py files each with different SITE_ID. As am developing, everytime I have to go through the 8 settings files and start up the runserver one by one to do full testing and navigate between the sites. </p>
  
  <p>Is there a way for me to run them all at once? I tried to do a command line utility for that but the management.call_command interface does not allow to fire off a process in the background. </p>
  
  <p>Any ideas how can i build something?</p>
