Python uses garbage collection to reclaim unreferenced objects (for most
objects that simply means reference counting). Thus, there is no guarantee
that the object will be deleted at a particular point in time.
Some other part of the program may still refer to it, and even if not,
the cleanup may be implemented differently.
