No, I was thinking about a "per-class" counter. Actually, a counter is not needed. A simple boolean is suffucient (one boolean per gc generation in each class), so the cost would be a single inconditional memory write per object allocation. I would think that this would be lost in the noize of object field "zero" initialization. No? Etienne -- Etienne M.
