This is not clear to me. The unwelcome duplication for this case
would consist only of the 64-bit shared libraries' own text & data -
and not the data of the 64-bit apps themselves. Thus having x32 on
the system is still a win *if* the memory savings from the x32 apps is
larger than the duplicated 64-bit shlib text/data.
