Yes. The two functions (privacy_proc and privacy_inet) can be
collapsed, as they look now, into a single function. However, we
might want to handle the privacy filtering different for each,
so they are in their own routine.

I suggested that. The code provided is an implementation that will allow
us to build newer designs more easily into the system, as oppsed to the
discussed ``kern.showallprocs'' knob.
