Django 1.8's reset_warning_registry (which we backport) was generating `RuntimeError: dictionary changed size during iteration` in Travis tests under Python 3.x. Likely a thread-safety issue on sys.modules.values(). See https://code.djangoproject.com/ticket/21049 for fix applied elsewhere in Django.
