[Zope] Zope 2.9 Product Refreshing

[Chris McDonough]

The real effort towards making a "better refresh" should likely be  
spent at the level of the Python interpreter.  The dynamic nature of  
Python is the thing that allows for a "refresh" in the first place,  
but the implementation of Python object references limits its  
usefulness.

The implementation of "reload" could be vastly improved by changing  
Python internally to allow for a sort of mark-and-sweep reload that  
could traverse an object graph full of references between an object  
and the modules that it is declared in.  Anything else will likely be  
too fragile to work in all cases.
