Comment (by tunixman):
If you're not enforcing uniqueness constraints in the database you're
going to have this race condition no matter what. Perhaps the
documentation around creating models and the basics of the tutorials could
be updated to reflect this. Documenting it as something endemic only to
these methods does nothing to improve the data consistency of Django
applications and would rather just discourage people from using these
methods which are basically the codification of the proper way to handle
these cases along side proper database implementation.
