I am not objecting directly! 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!
