It's not coincidence that the chapter of my book I convinced the 
publisher to release as a sample is the one that covers this area; this 
mess has been visibly approaching for some time now.  I'm going to put 
RHEL6 onto a system and start collecting some proper slowdown numbers 
this week, then pass along a suggested test regime for others.
