This bug can be reproduced very easily:
import pickle
class MyClass(object):
pass
m = MyClass()
m2 = MyClass()
s = set([m])
m.foo = set([m2])
m2.foo = s
print pickle.dumps(s)
This bug is critical as the pure-python pickle module is required when
trying to remove warnings in -3 mode with Python 2.6, which is something
that will be very common in the near future. It's easily reproducible
with simplistic object cycles like that of the above, in 2.5, 2.6 and
3.0 at least.
