625 * How we randomize polls. The poll interval is a power of two.
626 * We chose a random value which is between 1/4 and 3/4 of the
627 * poll interval we would normally use and which is an even multiple
628 * of the EVENT_TIMEOUT. The random number routine, given an argument
629 * spread value of n, returns an integer between 0 and (1<<n)-1. This
630 * is shifted by EVENT_TIMEOUT and added to the base value.
