The documentation for queryset field lookups in 1.0 (http://docs.djangoproject.com/en/dev//ref/models/querysets/#id7) is self-contradictory. Under EXACT, it says that the semantics of idexact=Null has been changed in 1.0 to mimic the behavior of idisnull=True. Under ISNULL, it says that idexact=Null never returns anything (the old behavior).
