Yep.  Though if we're going down the mitigation route, the move to 24.8 
work should really be a move to a compile-time selection of precision 
and type size -- would be nice to be able to use 64-bit types if 
necessary (though that would mean needing to use 128-bit intermediate 
types in a few places, I think).
