We need post-command-hook anyway, to add or remove the timer depending 
on the last command. I don't recall the exact reasons for the choice 
between the idle and non-idle timers, but flyspell comes to mind (and 
its use of sit-for).

Maybe that's enough. What if the user moves the Emacs frame around with 
a mouse, without resizing? Will the tooltip window follow?

They won't support the new style tooltips anyway.
