What do you mean by "deferred"? RC increment when taking a 
reference from the heap, but not when the reference is taken from 
the stack + periodic stack scanning?

Actually, in C++ (and to some extent in Objective-C) you minimize 
reference counting by using programmer knowledge. You increment 
when you take it from the heap and from thereon you use a 
borrowed (raw) pointer down the call tree.

Anyway, the key problem is not solved by "deferred RC". The key 
problem can only be solved by segmenting the heap in the type 
system.
