Sure it can: references that do not get destroyed.
Actually iptyhon does leak memory by default: the result of each command
you enter are stored in the _%i variable, where %i is the number of the
prompt. And if you return huge results without storing them in a
variable that will get garbage collected, you leak memory quite badly.
That's a feature, not a bug (:-P), but it is easy to work around, simply
delete those variables.
