We already have that big global lru queue (actually, it's a
bit more closer to second chance replacement).
For pages which are in the page tables of processes, we
put the pages on the queue when we scan them and they
weren't used since we scanned them the last time (NRU
replacement). After that, they go through the lru queue
and are reclaimed when it's their turn.
