I don't understand the details of the feature you are requesting.
Suppose `message' is being repeatedly called by some Lisp program in
quick succession -- what would you like to be actually displayed? only
the text of final message? If so, why is that a good idea? Most
"good" uses of fast echoing display very similar messages, like
"Updating... NN% done", where only the number changes. It would be a
pity to lose this checkpointing feature, IMO. So you will probably
say that there should be a variable to be bound to select one behavior
or the other. But if Lisp code needs to bind a variable to avoid the
flashing of different messages, why not avoid those messages in the
first place?
Your original report says:
I haven't done actual timings, but I'm finding that I have a *very*
strong perception that when emacs is writing lots of messages, it
slows down considerably.
Redisplay always slows down, but on any modern machine displaying only
the echo area should take a few milliseconds at the most, so I'd be
surprised if some real slowdown was involved. If you can show some
timings, please do, as there could be a bug or misfeature somewhere.
Anyway, can you describe the situation in which you see these flashing
messages? The only one I can think of is when Emacs starts up and
restores a previous session. Is that your use case, or did you see
this in other situations?
