That is really backwards :-O

In your class init, you override dispose on YOUR COPY of the GObjectClass
struct with myobject_dispose.

then you obtain a pointer to the IN TACT / READ ONLY copy of the GObjectClass
struct with g_type_class_peek_parent.

then in your dispose implementation which is called on YOUR COPY of the
GObjectClass, you chain up to the IN TACT function which still resides
in the READ ONLY `parent_class' pointer.

Does that clarify things ?
