    I'd like to keep 250 for a simple reason : the period is an integer
    number of milliseconds. I find it very convenient to be able to convert
    jiffies to ms. It serves at several places, for instance, poll(). In
    fact, what I like with 250 is that there is no divide between ms and
    jiffies, but just a bit shift.
