I was just playing it safe; I wasn't sure at what frequency the X server overhead you mentioned became a concern. If 8000hz is under that threshold, I entirely agree with that suggested value.

Otherwise, why do we need to worry about `freq` if it's hardcoded to TICKSPERSEC = 1ms? I see a lot of other occurrences where we pass NULL here.
