A GC is unable to guess that a programmer is not using a given object. To be eligible for GC the object must not be (strongly) referenced - that is it. Different GCs are tuned for different scenarios - typically balancing throughput and latency. I know of no GC that uses a "strategy" of waiting til program exits to reclaim memory.
