7bb5ce4 provides a workaround, but we should leave this open until the PR in django-redis is merged in, and then we've upgraded django-redis in our requirements file (and removed the pinned version for redis) accordingly.

The Django-redis PR is merged and upgraded in the requirements file. The version of redis has also been updated.
