It was not me who singled out this particular package; it was singled
out before, with the frequency hard coded to be 1 second. I just made it
more flexible and correct a misused plain `message'.

I've never seen how these information can be useful (ideally I would say
concealing all these cpp-progress-message unless some debug option is
turned on), but I'm probably not qualified enough to make such

One annoying case is that I've set up to show the syntax error at point,
but the "Parsing...done" message frequently comes in the way before I
can read the message.
