[PD] poor performance when saving an abstraction when many copies are loaded in a patch

no, i asked that objects share the same $0. objectclasses themselves don't 
have a $0.

I've never spoken about inheritance among instances themselves.

The idea is that you want to include the behaviour of a superclass into a 
class, because that's what the concept of superclass is about. Because the 
behaviour of an abstraction is in the patch of that abstraction, you need 
to load both the patch for the superclass and the patch for the subclass 
and connect them together. Inheritance requires that both those loaded 
parts are considered as one instance. If you give them separate $0 values, 
then it's not inheritance: the usual name for that is then «composition», 
and it's the normal way of doing pretty much everything in pd.
