+1 to mtredinnick's idea for just adding a flag to the post_save signal. The patch I attached does exactly this, and uses a variable that already existed in the save() method that held this information anyway (it was missing one place it needed to be set, so the patch handles that as well), so the additional overhead should be nothing.

Unit test for all model signals, including testing the post_save created keyword

The django_unit_test_model_signals.diff includes a unit tests for the Django test suite covering the following signals:
pre_save post_save pre_delete post_delete
It verifies that these signals fire in the proper order, that they have the expected instance of the model, and that the created flag on post_save is correctly set.
As far as I could tell, tests for these signals do not exist anywhere.

I'll take responsibility for cleaning up this ticket for the sprint.

There was a general consensus in a recent django-dev thread about this. No core developer spoke against it. The only question is whether to make it a new signal, or a flag attached to the post_save signal (signal emissions are not free). I'll have to rummage through the archives. Marking this as "accepted" though, since it's reasonable.
