I am aware of a few users who are (or at least were) using cpu and cpuacct separately because they want to be able to account without control. Having said that, there are tons of flaws in the current approach, because the accounting without control is just plain wrong. I have copied a few other folks who might be able to shed light on those users and if we should still consider them. [And the lesser number of controllers, the better it is!] Thanks!
