An special attention with circular references, ie, one interface whose
instance holds a reference to another interface whose instance ... holds
a reference to the first one. The result is an island of leaked objects.
There are afaik three ways to solve this problem: garbage collection, an
algorithm to detect the island or one weak reference in order to break
