documentation
"
    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.
