What you are describing is a compacting GC and not a

just describe in words how you would do a generational GC

tracking pointers
within the old generation that point to the new generation.
It was a generational gc, I described earlier how it used page
faults instead of write barriers. I eventually removed the page
fault system because it was faster without it.
Page fault ARE write barrier.
