   GCC's GC promotion of poor locality of reference is not proof that
reference counting is the only way to improve that locality of reference.
It doesn't matter what allocation/reclamation scheme you switch to, if it's
not used in a way consistent with the cases it optimizes for, it's going to
stink.  There's just as much reason to believe there's a generational GC
that will do what you need as to believe reference counting will be some
kind of magic bullet (without the brittleness).
