And there's no hourglass pointer in terminal Emacs (which apparently is
almost as popular as GUI Emacs for some reason), so perhaps it's worth
having a spinning thing somewhere.  In the mode line, for instance.

However, if we want that, perhaps it shouldn't be tied to
with-delayed-message, but work exactly like the hourglass -- i.e., start
spinning whenever Emacs is busy for a while.

I'm not at all sure whether there'd be any negative repercussions to
spinning a glyph in the mode line area (for instance -- what about if
you're running over a slow ssh connection?), but perhaps it's worth
exploring and see how goes?
