For one thing, if a page has not been modified since it was paged in, and it's slot on backing store has not been reused, it can be assigned to another address space without first writing it to disk. I believe this is called "page-stealing". On Mon, Jul 2, 2012 at 10:14 AM, Edward Jaffe wrote: >

As Tom Marchant has already pointed out, Hobart Spitz's view of page stealing is mistaken. Perhaps even more important his view of how the ASM [Auxiliary Storage Manager] works is also mistaken. No page that has not been modified is paged out. (One of the minor but important merits of reentrant
