[lug] automatic renice?

[Bear Giles]

After I wrote that I realized that the most general way of handing 
that is to treat the arguments as the program (with arguments) to 
run, not hardcode the application to be run.

It would be a lot like 'sudo', but with only one action.

That raises another question - why not use sudo with a restriction 
that the only program that can be run is 'nice'.
