title: How to run own daemon processes with Django?
body: <p>In my Django project I have to do repeatedly some processing in the background.
  This processing needs access to Django stuff, so I put it into Django's commands and run it as cronjob.
  Right now I realize, that I have to do some of them more frequently (cronjob has limitation to invoke command at most every 1 minute). Another problem is that I don't have enough control, to protect running the same command in one time. It's happen when one processing takes longer than one minute.
  I think that I should run them like daemons, but I am looking for pure way to do it with Django.
  Have you ever faced with this problem or know any clean solution for it?</p>
