Marc-Andre Lemburg <mal at egenix.com> added the comment:

The hash-attack.patch solves the problem for the integer case
I posted earlier on and doesn't cause any problems with the
test suite.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
KeyError: 'too many hash collisions'

It also doesn't change the hashing or dict repr in existing
applications.
