Devin,

I think the issue David is trying to address is that no deleteGroup is  
sent to children groups if the parent is deleted (which should  
probably be considered a bug anyway). Assume you have this group  
hierarchy:

Group A
     Group B
     Group C

If you delete Group B then Group B receives the deleteGroup message as  
does Group A (unless Group B traps the message).

If you delete Group A then Group B and Group C DO NOT receive the  
deleteGroup message. Only Group A does.

Currently a developer needs to to manually go through a group's  
children and dispatch the deleteGroup message to it's children if it  
was the target of the deleteGroup message.
