I forgot to mention that this would also add loopback cellptrs for
the two cells pointed to by __builtin__.abs and __builtin__.max.

But hey... in that case the cellptr is always two steps away from
the object.  So why not just use PyObject**s instead of cells?

    dict -> ptr -> ptr -> object

(Or, if we want to maintain backward compatibility with existing
dictionaries, let a cell be an object, so we can check its type,
and have it contain just one pointer instead of two?)

Am i out to lunch?
