Wrong. The memory allocated can never be used for other objects than
ints, but it will be reused for other ints. IOW if you do
for i in range(100):
you only allocate space for 1000000 ints, not for 100 times 1000000
ints. (The range(100) OTOH are all in a cache that make the objects
indestructible, but this only applies to values in [-5, 100).
