My intention is that even under such an aggressive scheme,
* No cost would be paid unless you are using objects with
finalize methods
* The cost for objects with finalize methods would be primarily:
- longer latency before finalize is invoked
- occasional need for global synchronization
with the ability to trade off between these two points.
Do you think my proposed semantics for finalize would have effects
other than those mentioned above?
