The only cases in which this would really be useful is when running some 
software which once in a great while goes super prompt critical and starts 
throwing processes of a known name format in all directions, or when you have a 
problem and know the process names involved before OOM kills everything in sight.

This does have a strange attraction, I did save the patch in case another "every 
few years" problem comes up.
