10can be used by the super-user to alter the
11priority of a running process.
12By default, the nice of the process is made ``19'' which means that it
13will run only when nothing else in the system wants to. This can be used
14to nail long running processes which are interfering with interactive work.

17can be given a second argument to choose a nice other than the default.
18Negative nices can be used to make things go very fast.

26If you make the nice very negative, then the process cannot be interrupted.
27To regain control you must put the nice back (e.g. to 0.)
