HI all, I've realized that the nice(1) code hasn't been modified for a long time (last code change seems from 4 years ago according the sources). ¿Is the nice(1) behaviour the expected? I mean, ¿Has been the ULE scheduler adapted to nice(1) command or not? nice(1) is a very old command based on old concepts and created in times when SMP didn't exist. So ¿it works correctly when a modern an re-designed scheduler as ULE is used? Maybe I have to read again this paper: http://www.usenix.org/event/bsdcon03/tech/full_papers/roberson/roberson.pdf -- I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain. Bene Gesserit Litany Against Fear.
