Hmm, that's what I originally thought too when I designed the
ObjectManager stuff but I think it's wrong. I mean, the intention is
to match any message that concerns a path (not argument) that matches
the glob /org/app/subtree* - this doesn't have anything to do with
arg0path since the message may not even have any arguments. Right?

(Thinking more about it, we probably want pathSubtree=/org/app/subtree
instead of pathGlob=/org/app/subtree* since it's more efficient to
implement that way.)
