Right.  I was more thinking of whether to evaluate the text form first
or when displaying it.  I.e., 

  (with-delayed-message 2 (format "This is taking a long time, %s" 
(user-full-name))
    ...

so this form will have to evaluate that immediately (before starting the
body), but display the results when the atimer runs out.

I'll have a crack at implementing this and see how it goes...
