249            cyclic references. The objects would have been eventually
250            collected by the garbage collector but too late. One symptom is
251            that when layers are removed so that the last normal reference
252            owned indirectly by the session to a shape store goes away, the
253            shape store is not actually removed from the session even though
254            the session only keeps weak references because there are still
