摘要：
Disclosed is a computer implemented method and apparatus for marking as critical a virtual memory page in a data processing system. An operating system indicates to a virtual memory manager a virtual memory page selected for paging-out to disk. The operating system determines that the data processing system is using a cooperative memory over-commitment. The operating system, responsive to a determination that the data processing system is using cooperative memory over-commitment, marks the virtual memory page as critical, such that the virtual memory page remains in physical memory. The operating system, responsive to marking the virtual memory page as critical, sets the virtual memory page to a page-out state.
