django model: objects.all().delete() doesn't

I am trying to clear out and reload a table in my django model, and

>>> models.PuzzleSum.objects.all().count()
2644
>>> models.PuzzleSum.objects.all().delete()
>>> models.PuzzleSum.objects.all().count()
2535

... wtf? Always the magic number 109. I know I could just go into the database and delete them by hand (or loop until they're all gone) but I'm curious.

(Django 1.3.1 on Mac OS X Lion btw)
