/*

 *	This magic constant controls our willingness to transfer

 *	a process across CPUs. Such a transfer incurs misses on the L1

 *	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.
