Since objects are union, the addition makes ALL objects bigger.
RArray already reachs the limit.

aux.shared has no problem, since shared arrays should share
default value also.  But array with default value can't have
capacity.

It may be possible to add reference to extra struct in aux, or
with generic ivar.  But the former looks complex and the latter
makes speed penalty for each array access.
