I guess it depends what the implementation actually does.  What does HZ
even control these days?  If it controls the scheduler timeslice then
yes I very much do need 1kHz, xserver needs to be able to post a buffer
swap at least every 16ms and if the scheduler only task-switches every
10ms then I stand a very good chance of dropping frames.

Why do you want it lower?
