You want su1, or maybe sudo.

Remember: xmms might be configured to spawn the shell plugin.
I guess there should be a maximum renice value ulimit instead, which would allow running allmost any user task on a higher nice level, except the important stuff, with the additional benefit of being able to temporarily renice some tasks until the more important work is done.
I remember something similar being discussed for realtime tasks, but I don't remember the outcome. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
