* This magic constant controls our willingness to transfer

* cache, and on a P6 or P5 with multiple L2 caches L2 hits. My
* gut feeling is this will vary by board in value. For a board
* with separate L2 cache it probably depends also on the RSS, and
* for a board with shared L2 cache it ought to decay fast as other
* processes are run.
