The three lines I sent:

(setq icomplete-separator "\n")
(setq icomplete-prospects-height 10)
(add-hook 'icomplete-minibuffer-setup-hook (function (lambda () (setq resize-mini-windows nil) (enlarge-window icomplete-prospects-height))))

had no other purpose except demonstrating that (setq resize-mini-windows 
nil) solves the problem of disappearing prompts.  Of course I do not 
consider that these lines should be blindly used, in fact I wrote "It 
needs some tweaking, but it works."  Indeed one should do something with 
user preferences, and use a setq-local.  The point is that doing this is 
much simpler than trying to calculate the height of the completion 
candidate list, which amount (as Stefan wrote) to redoing what redisplay 
does.
