It would mean that the resistance to switching to 1000HZ gets massively
reduced.

Basically, the current implementation stops the timer tick when the
machine is _idle_. This means that we're not waking the machine up every
1ms and wasting power, and that was the main reason we didn't want
HZ=1000 in the past.
