So that they can for example limit a particular user to 50% cpu time. I spent last week with testing and I fixed some witness complaints. I also improved the %CPU statistics counting - the 4BSD scheduler I am now working with updates the %cpu usage statistics once a second for every thread. Now I also count the data from the yet unfinished second. I think I am now done with per-process %cpu limits and this week I start working on per-user cpu limits. rudo
