I think this is basically sound, but bear in mind that the yarrow
kernel thread, which processes the entropy buffers into yarrow, loops
with a 100 ms pause. You have to allow enough time for that delay and
additional time for the queues to be drained and the yarrow reseed;
otherwise you are discarding the entropy (assuming you haven't already
done that by saturating the buffers with sysctl -a).
