Keep in mind, sys.getsizeof(obj) returns only the size of the given
object.  Any referenced objects are not included.  You can get the
latter from gc.get_referents(obj).

PS) The asizeof(obj) function from this recipe <http://
code.activestate.com/recipes/546530> does size the object plus its
references, recursively.
