It looks like you're trying to run the dev server as a real web server, which is a very bad idea (it's only serves one request at a time, for starters). As it says here:
http://docs.djangoproject.com/en/dev/ref/django-admin/#runserver-optional-port-number-or-ipaddr-port "DO NOT USE THIS SERVER IN A PRODUCTION SETTING. It has not gone through security audits or performance tests. (And that's how it's gonna stay. We're in the business of making Web frameworks, not Web servers, so improving this server to be able to handle a production environment is outside the scope of Django.)" Is there a reason you can't use Apache, or a different server with a WSGI or FCGI setup? If you're not running it in production, why do you need daemontools?
