hi,

I have an interface, where I share some data between the instances.  
the data is created on first access. Now I also would like to release  
it when the last instance goes.

problem 1: base_finalize() is not called for static types

I thought that I could do some own ref-counting and then do  
g_object_weak_ref on the instances to decrement the ref-count.

problem 2: There is nothing in the GTypeInfo for an iface that is  
called for each new instance (using instance_init causes  
g_type_register_static (G_TYPE_INTERFACE,...) to fail as one does not  
really instantiate the iface, but the type that implements it).

Any ideas?

Stefan
