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.
