I didn't know about progress-reporter, so my time wasn't wasted, at
least. :-)
But I wonder whether a simpler, more general function would be
possible. If we're outputting stuff that's not a percentage,
progress-reporter doesn't help much.
`message' could work as follows:
If it's been less than (say) 50th of a second since the previous
message, then don't message anything. However, set up a timer in a
100th of a second's time to display that message -- if nothing else has
been displayed in the mean time.
The net effect will be that normal messaging (where it's been a long
time since the previous message) is displayed as usual, but when we
enter a "high-message" storm, we start skipping messages. But we always
end up showing the final message, anyway.
This would be a very simple interface for programmers to deal with
(i.e., "don't worry about it"), and the user wouldn't notice anything in
particular -- other than Emacs being faster in some situations.
