As I said in my previous email, my TreeItem is bound to resources other  
than memory and this kind resources must be released synchronously - the  
GC would usually intervene too late. For instance, the TreeItem might  
subscribe to events that are used to update its state, and unsubscription  
must happen when the TreeItem is no more used, otherwise bad things can  
happen.
