I don't understand the point of feeding boilerplate into Yarrow. Yes,
it will stir Yarrow's internal state but it does so in a predictable
way so it doesn't add any entropy.
On the downside, it doesn't appear to be possible to queue more than
4KB of input every 100msec - excess input is just discarded. This
implies that feeding boilerplate into /dev/random just increases the
probability that real entropy will be discarded.
