Is there any work going on with regard to making Django more resilient
in the face of changes to dictionary ordering? I know there has been
discussion about the hash collision issue last December, but I'm
unable to find a summary of the official Django position on this. Can
someone please point me to it? My Google-fu may have deserted me.
Following recent changes to the in-development Python 3.3, several
dozen Django tests are failing, apparently because of changes to
dictionary hashing and hence key order. Some examples:
======================================================================
FAIL: test_proxy_model_included
(regressiontests.fixtures_regress.tests.TestFixtures)
----------------------------------------------------------------------
Traceback (most recent call last):

'secret'}
+ VALID: {'username': 'adrian', 'password1': 'secret', 'password2':

There are no corresponding failures with Python 3.2. The Django 3.x
branch is pretty up to date with trunk.
