Fixed #18676 -- Allow fast-path deletion of objects

Browse Source 
Objects can be fast-path deleted if there are no signals, and there are
no further cascades. If fast-path is taken, the objects do not need to
be loaded into memory before deletion.

Thanks to Jeremy Dunck, Simon Charette and Alex Gaynor for reviewing
the patch.

@@ -149,6 +149,12 @@ Django 1.5 also includes several smaller improvements worth noting:
* Django now provides a mod_wsgi :doc:`auth handler
</howto/deployment/wsgi/apache-auth>`
* The :meth:`QuerySet.delete() <django.db.models.query.QuerySet.delete>`
and :meth:`Model.delete() <django.db.models.Model.delete()>` can now take
fast-path in some cases. The fast-path allows for less queries and less
objects fetched into memory. See :meth:`QuerySet.delete()
<django.db.models.query.QuerySet.delete>` for details.
