Here is a slightly updated skeleton that I had put some work into and 
not yet posted.  Here are two packages (installable by pkg) that are the 
most current version.  Between the last published versions and the 
current version, I've worked to make this more vectorized because the 
main problem seems to be the implementation speed.

If someone could try to adapt to C++ the functions that directly touch 
the handles (anything that uses the __uiobject_globals__ script: delete, 
get, ishandle, set, __uiobject_create_object__, __uiobject_grow_list__, 
__uiobject_handle2idx__, __uiobject_move_object__, and 
__uiobject_update_timestamp__) then I think that would have the most 
significant impact on speed.  Some of those are obviously very internal 
functions (__uiobject_grow_list__, __uiobject_handle2idx__, and 
__uiobject_update_timestamp__), and they may not need to be directly 
re-coded in C++.
