Sorry, I don't think I follow: what did you want to fix in this
scenario?

I'm guessing this is about the timer you proposed that would remove
the text shown by minibuffer-message.  If so, my point above was not
about the time it takes to remove that text with the current master,
my point was that while the message is displayed, the icomplete-mode
candidates are not displayed.  (FWIW, I don't consider this a bug we
should fix, and neither does Stefan, AFAIU.)

Am I missing something?
