[NTOS]: Assign the working set list address, system-wide, but per-process (in hyperspace). [NTOS]: Give every process its working set page, and store it. Build a bogus working set list (MMWSL). [NTOS]: Use the process working set list (MMWSL) to track page table references during faults, just as Windows does.
