      Description

      Contents of closed Archive regions are supposed to be always live. Currently G1 marks through them anyway. See if there is a cheap way to avoid that.

      One option to avoid marking and scanning through the could be setting ntams to bottom at mark start.

      Full GC already does not mark through these regions.
