Copying garbage collection can be improved by identifying long-lived heap objects and allocating them in an area of the heap that is not collected. What compile-time analyses can be done to identify heap objects that will be long-lived? At run-time, how can we efficiently estimate the "age" of a heap object (so that long-lived heap objects can be specially treated)?
