int type of Python 2 uses an internal "free list" which has an unlimited size. If once you have 1 million different integers are the same time, the memory will never be released, even if the container storing all these integers is removed, because a reference is kept in the free list.

This is a known issue of Python 2, solved "indirectly" in Python 3, because "int" type of Python 3 does not use a free list. The long type of Python 2 does not use a free list neither.
