System for page-out and page-in of stale objects in memory

摘要

A system for moving an object from a short lived memory area in a program address space on a physical memory into a tenured memory area in response to a determination that the object has not been freed from the short lived memory area. If the object in the tenured memory area is determined to be stale, then the object is moved to a native memory area in the program address space. If the object in the native memory area is referenced by a processing unit, then the object is moved into the tenured memory area. If the object in the native memory area is not referenced, then it will be determined if page-out to a page file on hard disk is required. If the object is referenced in the page file, then the object is moved to the program address space.
