However the class itself is not.  This is particularly problematic when using the Django test runner with the `--parallel` option enabled when a `Model.DoesNotExist` exception is raised. The result of this is the test runner bailing with a `pickle.PicklingError`, making it exceptionally difficult to debug the cause of the `Model.DoesNotExist`.
