I glossed over a lot of big details:

- zones
- type of pages: anonymous, swap cache, file, high, buffer, ramdisk
- interaction with page cache
- various flavors of swap-in and swap-out paths
- shared memory and the swap cache
- locking strategy
- aging strategy
- scanning policy
- deadlock and livelock avoidance measures
- unloaded vs loaded behaviour
- effect of load changes
- out of memory handling
- clustering (or lack of it)
- IO throttling

Each of these is a topic all by itself. You'll find all of them
discussed extensively here on lkml.
