You're right that CFINTnn is more than just the 'CPU Burn' job.  If I 
understand it
correctly, CFINT stands for something like "Command Function INTernal" and is
essentially just an accounting entry that causes the performance tools to charge
System Internal CPU cycles to a big bucket called "CFINTnn" (where the nn equals
processor number).  This would explain why people report large amount of CPU 
usage on
non-server systems, and may also explain why some really bright people have not 
been
able to locate and change the legendary CFINTnn job.  :)
