Why can't we split harvesting entropy from /dev/random from harvesting entropy from sources that are much more performance-sensitive? Currently random_harvest_internal() is used for both and it is trying to be fast, as we don't want to slow down the caller. But with /dev/random the caller won't mind to be slowed down. --=20 Pawel Jakub Dawidek http://www.wheelsystems.com FreeBSD committer http://www.FreeBSD.org Am I Evil?
