I've noticed this same behaviour as well but only with a higher loaded
production server and using the gunicorn gevent class, i've never seen this
happen with a sync class.
I'll take a wild guess that gevent worker class is handling requests before
django has had a chance to initialize. Perhaps django does some sort of
blocking on startup and the gevent monkey patching prevents this blocking
behaviour on startup. Just a wild guess.
