Relax.  Earlier in this thread I seem to remember you were advocating
certain experiments in spite of the skeptics.  So give the GC experts a
chance.

As I understand it, generational collection ought to improve locality,
since the youngest generation can be collected frequently, and may even be
small enough to fit mostly in cache.

(I've never observed it to work in practice, but don't let that
discourage anyone :-)
