The 'C' column is quite useful when tuning SMP systems, and something I 
frequently look at when debugging performance issues in 5.x and 6.x. 
Given that 'NICE' has a maximum width of three characters (-20 - 20), I 
wonder if we can abbreviate that as 'NIC' or 'NCE' or such to reclaim one 
character.  On WCPU/CPU -- losing one of those should be fine.
