Does this effect GC performance even if you don't use finalizers?
My knowledge of how finalizers affect GC performance is limited but
now and then I stumble on some Java article (e.g. ) that claims
that they can slow things down. That's no problem if there's no
additional cost added to code which doesn't use finalizers.
