I don't know how that would be possible. Once the news-check script has
completed, it has no power to do anything, so it would not be able to
set up another idle timer.

The script has to finish, otherwise emacs would be unavailable to
use. So it has to prepare the next run before it finishes. Unless I set
up many idle timers in advance, say enough to last 24 hours?
