/* * These are the constant used to fake the fixed-point load-average * counting. Some notes: * - 11 bit fractions expand to 22 bits by the multiplies: this gives * a load-average precision of 10 bits integer + 11 bits fractional * - if you want to count load-averages more often, you need more * precision, or rounding will get you.
