There's absolutely nothing wrong with "jiffies", and anybody who thinks

msleep(20);

timeout = jiffies + HZ/50;
just doesn't realize that the latter is a bit more complicated exactly
because the latter is a hell of a lot more POWERFUL.
But if all I really want is to sleep for 20ms, what does the additional
power actually buy me?
