approximates waste by unreachability which is less timely than asap’s approximation by Access.
I think a more careful reading of the work is required to distinguish the precise meanings of "unreachability" and "access" in this context.
- unreachability means there's no live reference to that object.
- access means somebody is going to use this object again. If you have a live reference but won't ever use it again it's a kind of leak (that's how GCed languages can leak memory without any manual management).
