I don't like this. I really cannot imagine any situation for which the
compiler can't resolve SIZE to a compile-time constant. I think it's
pointless to have a dispatch routine that just calls all of
its a library call for arbitrary sized objects... C++ can have any
class declared atomic, so it doesn't have to map to one of those
optimized lock-free routines.
