I think my definition of virtual memory might be out of synch with
others. Cheap large memories mean that we would be able to do away
with demand paging. We would still need address translation unless
every process was written in position independent code (no address
constants at assembly/compile time etc.) Does virtual memory imply
demand paging or just address translation?

Isn't it interesting how the beautiful little red flower in the forest
becomes so ugly when you discover it's a candy wrapper.
