Early pages were 1K.
Do systems with huge pages page in the move-them-to-disk sense I wonder? I assume they
don't in practice because it would be insane but I wonder if the VM system is in
theory even willing to try.
Something I never completely understood in the paging vs swapping thing was that I think
that systems which could page (well, 4.xBSD in particular) would *also* swap if pushed. I
think the reason for that was that, if you were really short of memory, swapping freed up
the process structure and also the page tables &c for the process, which would still
be needed even if all its pages had been evicted. Is that right?
