Just for reference (I'm sure you know, but others might not): BogoMIPS are
measured using a busy loop because that's precisely the number the kernel is
interested in -- it's used to know for how long to loop when doing small
delays in the kernel (say, "sleep 20 microseconds"), which is done using a
busy loop.
