Is it clear why their not freed, even though UniqueRepresentation only puts a *weak* reference to them (it uses a weak value dictionary)? In any case, it is possible to explicitly clear the cache of a UniqueRepresentation. But this would only help if there is a strong reference pointing from the dictionary key to the corresponding item.
