        Currently, G1 discards the last region promoted to after an evacuation pause and it does not re-use it during the next evacuation pause. This can result in a lot of half-full regions residing in the heap. We should ensure that the last region promoted to during an evacuation pause is also the first region promoted to during the subsequent evacuation pause. This was, G1 will utilize the heap a bit better.
