It generally does for python 2.5+. In python2.4, for example, PyInt was
allocated in its own groups. And those groups were never freed back to
the OS.

There are a lot of complexities for the python object allocator. But
*most* of the time, things get returned to the OS. (small objects are
allocated differently from 'large' objects,
tuples/sets/dicts/ints/floats all have custom allocation pools, etc.)
