Comment (by Alex):
Ok, the problem here is that you can't use LIMIT/OFFSET in a delete()
query (look at the assert at the top), nesting this works around it, but
clearly breaks the invariant that the query will return the same items on
every execution (less those that have been deleted). An extra count() on
every delete is clearly unacceptable, so I'd have to say that we need a
way to raise an exception here.
