Bleh. If anything you may as well lose it - manual memory
management is the only option to guarantee you something to the
extent of having related object together in the same page. That
is if you can make it so by hand.
Under what assumption? There is not optimal garbage collector,
you have to select or adapt one that fits the application.
You can tag objects by a group id or type id and use that during
compaction.
write do *cost* something. This cost is then regained (with
interest) by applying simpler and efficient algorithms such as
semi-space compaction.
I wouldn't call semi-space compaction efficient, it can lead to
heavy paging.
