Apps registry is no longer auto-populated when unpickling models outside of Django
----------------------------------------------------------------------------------
The apps registry is no longer auto-populated when unpickling models. This was
added in Django 1.7.2 as an attempt to allow unpickling models outside of
Django, such as in an RQ worker, without calling ``django.setup()``, but it
creates the possibility of a deadlock. To adapt your code in the case of RQ,
you can `provide your own worker script <http://python-rq.org/docs/workers/>`_
that calls ``django.setup()``.
