I've created a proposal:

for simplifying and decoupling the persistence and cache architectures.
I've been thinking about this for quite some time. In fact, the ability
to subclass
weakref.ref objects that appeared in Python 2.4 anticipates this. :)
I like the proposal but I don't understand some details:
- Why do you want to use '__setitem__' method instead of for example
'notify'? Is it only for "make this go fast"?
- Why are such values selected for the state constants (persistent.GhostState
= None, persistent.ChangedState = True, persistent.SavedState = False,
persistent.ReadState = False)?
