I think I had my wording wrong. General redisplay works fine (I see
the cursor blinking and stuff like that), but the mode-line content
doesn't update if I'm not interacting. I guess what I want is to
`force-mode-line-redisplay' around once per second (right now, it goes
without update indefinitely if the user is not interacting, see
below).

I ran the following after emacs -Q.
(add-to-list 'mode-line-format
'(:eval (number-to-string (cadr (current-time))))
'append)
This adds a number to the mode-line which changes at every second. If
I'm typing text (or otherwise interacting) then I see it updating
fine. If I just take my hands off the keyboard, then the number stops
updating indefinitely.
