Doesn't set_time_scale() do exactly this by directly using the supplied
ticks_per_sec value? Why does it need to be scaled based on the old frequency
when the values can just be recalculated?
I removed the call to local_time_calibration() and it still works just fine,
so it looks like set_time_scale() overrides the other settings anyway.
I'm still having a strange issue (only in X sessions it appears) where the key
repeat rate and response time gets very slow after a frequency shift.
Everything else responds normally except for the keyboard, and that problem
goes away after a minute or two. Any idea what's going on?
