Agreed, but I don't have access to such hardware.  However this won't
influence the memory overhead part, and there is already frequent
problems with that, especially since declarative partitioning, so I
don't see how we could afford that without some kind of cache TTL or
similar.  AFAIR the last discussion about it a few years ago didn't
lead anywhere :(
