                    Currently refinement is based on current mutator activity, which may cause needless re-refinement.
Actually it is only required to try to get the number of scanned cards down to a minimum just before garbage collection. The remaining time they can sit on the card table.
I.e. ideally only refine once completing just before gc. That could also fix/improve JDK-8368935.
