Page Replacement Policies
Several schemes are commonly in use:
- Least Recently Used (LRU)
- Most Recently Used (MRU)
- First in First Out (FIFO)
- Random
LRU / MRU require knowledge of when pages were last accessed
- how to keep track of "last access" time?
- base on request/release ops or on real page usage?
