Do you mean pages it isn't *currently* using, or has *never* used?
Also, note that VSZ refers to the virtual size, which may include
pages currently out on swap, while RSS refers to actually resident pages.
And then there's the other great bugaboo, shared pages that are mapped by more
than one process.
What exactly are you trying to do?
