Apparently /dev/random uses h/w PRNGs if available, discarding all other sources of randomness. This seems like a mistake to me - we should fix it. Also, it seems that entropy is available in detailed interrupt timing (see http://www.issihosts.com/haveged/) which might be useful on entropy-starved systems - I suspect we are not exploiting this source, and in light of recent developments, we probably should be, Comments?
