The file is already displayed "quickly enough". The problem arrives when
you try to navigate far from BOB (e.g. to EOB).
What's going to happen then, if the timer hasn't fired yet? And for the
timer's work to be useful, it has to had happened between the last edit
and the subsequent navigation. A lot of idle timers like that = a lot of
discarded work.
