The only concern I would have is access to the valueDictionary  
WeakRegistry  when processing the array at a low background priority  
since it may block the access to adding new elements. However a fix  
may be to add a shared queue that add: uses to place elements on.  
Later on the finalizeValues stick the elements in the value  
dictionary. However I'm not sure if other accesses to t he value  
dictionary might impact things.
