Hi Adam,
So given two memory models:
1. Linux virtual machine has enough virtual storage to run all programs it needs to without swapping, tiny swap space. 2. Linux virtual machine has small virtual storage and swaps often, large swap space.
Wouldn't CP be a better pager in Model #1 than having CP page the (smaller) VM in #2 and having Linux do it's own swapping as well?
Yes, if Linux didn't happy gobble up any available memory and use it as file cache. But it does, and there's no easy way to defeat this behavior. So you basically end up having CP carefully managing a whole bunch of pages of cached file contents.
