Hm, there can be a lot of objects with the same name. And many of them freed at runtime which makes it not so easy to track objects by names.. I have an idea that seems simple but effective: wipe out trace counters for addresses that are freed during GC. Yes, this needs a GC support. Hopefully, it would make us a good sampling for objects in older generations. Stack access can be filtered out without much pain.
