I see.  I didn't think about the GNOME example. While I knew that the
configuration file couldn't tell you everything about a running
instance, it was the only thing I could think of.  As I said earlier,
the man page doesn't seem to say anything about this.  Hopefully,
someone else with more knowledge can give you a better answer.
