      Description

        In some cases it is extremely useful wrt to pause time if G1 could pre-clean (remove) obsolete entries (the referent is NULL or the referent is live) from the discovered lists to reduce pause time.

        This is the same idea as CMS's j.l.ref.Reference precleaning.

        This can reduce Remark pause time (Reference processing time) very significantly.
