Sorry, I object to installing a timer-based solution at this time.  It
is too radical and is likely to cause numerous unintended consequences
all over the place.

I just suggested another possible solution: bind
'minibuffer-message-timeout' to zero when calling 'minibuffer-message'
from 'message'.  Would that work, or will it have some unwanted side
effects?
