No, Wolfgang is right about this. If showallprocs is false,
the only way to have processes shown that don't have matching
uids is to make use of super-user privileges, and thus is needs
to be accounted for.
BTW, the description referring to "normal users" could be improved;
after all there are no users which aren't normal. The autonicetime
node has some prior art: "non-root".
