Description:


HandleRegistries are like Registries, in that they watch for the death of
a registered object. However, they send a self-change notification, passing the registered
handle as argument, instead of creating a shallow copy and letting it do the finalization.
Use Registry for objects which know themself how to clean up;
use HandleRegistry, if someone else does the cleanup.


Instance protocol:

dispose handling
o  informDispose: someHandle
an element was disposed; let my dependents know about this

redefined to block
o  register: anObject
not useful for HandleRegistry - use #register:as:

o  registerChange: anObject
not useful for HandleRegistry
