What do you think of a model where there is a global "thread count" that keeps track of how many threads reference an object?

I've thought about that sort of thing before. The problem is how you keep track of how many threads reference an object, without introducing far more overhead than you're trying to eliminate.

Then there are thread-specific reference counters for each object.

What happens when a new thread comes into existence? Do you go through all existing objects and add another element to their refcount arrays?
