It might be useful for power consumption purposes, too.

For example, on my Core 2 Duo Allendale box, default FreeBSD
7.0-CURRENT consumes about 2W more power in the idle loop than
DragonFly BSD or OpenBSD due to the increased number of clock
interrupts that it processes...

Interesting point, thanks. How do you measure power consumption?
