Thanks, I've had a quick look at the source and it looks promising.
Unlike Turbid it doesn't try to produce high-quality randomness on its
own, it just contributes bits to the kernel's entropy pool. So I guess
the next question is, what happens if you contribute completely
predictable bits to the entropy pool? Would it harm the quality of
/dev/random to do so?
