A method of updating, directing or moving page table entry values in a virtual memory management system. The method operates without requiring suspension of a search process looking for a predetermined page table entry value of a page table. In a first step, the method determines whether the current page table value is the predetermined page table entry value or whether the search process looking for a page table entry value is in progress. Then, the current page table entry value is deleted or moved in the event that the current page table entry value is not the predetermined page table entry value or in the event that the search process is not in progress. Next, the method waits until the search process has completed looking for the predetermined page table entry value or for a predetermined period of time before deleting or moving the current page table entry value, in the event that the current page table entry value is the predetermined page table entry value or in the event that the search process looking for a page table entry value is in progress. |
