R. David Murray added the comment: Yes, it is (was) to break otherwise unbreakable GC cycles involving __del__. Many improvements have been made to these algorithms in python3, such that __del__ methods no longer create unbreakable cycles, although I believe a few cases still remain. Since some python interpreters do not do GC the way CPython does, it is always best to not depend on GC cleanup but instead to be explicit.
