Re: messages override minibuffer input

[Richard Stallman]

    My knowledge is limited when it can happen that messages can
    override minibuffer input. Initially, I thought only of messages
    from asynchronous processes like timer functions. Then I realized
    that messages can also show up that refer to my current minibuffer
    input.

In cases like this, the echo area message disappears after a
few seconds, or whenever you type another character.  So I think
those are not a problem.  Why do you consider that a problem?

What about the timer case?  Does the message disappear after
a few seconds, or whenever you type another character?
