I agree with that.  I think having this show up in verbose mode is a
really good idea - when something just hangs, users don't know what's
going on, and that's bad.  But showing it all the time seems like a
bridge too far.  As the postmortem linked above shows, people will
think of things like "hey, let's try --verbose mode" when the obvious
thing doesn't work.  What is really irritating to them is when
--verbose mode fails to be, uh, verbose.
