  I don't know for sure, but that's a good point. If I were real 
concerned about it, I'd write a small program that filters it out of both 
of those commands. Hardcode the executable to execute ps and w, which may 
be hidden as .ps and .w in some obscure directory. It's kind of an ugly 
workaround, but I doubt that disabling it is built into the code. 
Actually, now that I think about it, grab 'ps' and 'w' out of the source 
tree and just compile them without those options. That would mean chopping a 
simple 'cout' or 'printf' command in 'w' and a few lines that look like 
they cater to the '-U' option in 'ps'.
  Go with my second suggestion. I got carried away with that first one 
before I realized the obvious best solution.
