careful: it creates another dictionary structure with the same size as the first one, but it doesn't copy the objects in the dictionary. so whether it doubles the actual memory usage depends on what data you have in the dictionary (last time I checked, ints and dictionary slots were the same size, but I cannot think of any other object that isn't larger...)
