I'm glad that someone brought this topic up. I often use /usr/xpg4/bin/nice
as the root user to toss a process "into the basement" where it can slowly
rot as far as I am concerned. :-)
Like I need to bzip or gzip something large .. I do this
nohup /usr/xpg4/bin/nice -n +20 gzip -9 foo
then leave it to stew slowly on the back burner. It will get done
eventually and I am happy with that.
I have looked at the manpages over and over and even tried the examples. I
generally come away with a less than satisfied feeling.

I think that running a process with "real time" priority is dangerous unless
you really really know what you are doing.
In any case .. I'd love to see some real examples of how we can use this.
