+This method is atomic assuming correct usage, correct database configuration,
+and correct behavior of the underlying database. However, if uniqueness is not
+enforced at the database level for the ``kwargs`` used in a ``get_or_create``
+call (see :attr:`~django.db.models.Field.unique` or
+:attr:`~django.db.models.Options.unique_together`), this method is prone to a

+If you are using MySQL, be sure to use the ``READ COMMITTED`` isolation level
