Does a page become resident but unmapped after a page-in?

Don't think so (if I understand what you are asking). A page-in makes it both resident and mapped for the requesting process.

What is a resident, but unmapped page?

IIRC the need page exists in physical memory already but it isn't currently mapped into the requesting process. -Shawn _______________________________________________ Do not post admin requests to the list.
