Moreover, /dev/random can be used only for initial state table computing, not as random() call replacement due to 1) slowness of /dev/random device access 2) eating all true random bits which may be needed for other applications too. I probably will try to modify devsrandom() posted by Garrett to work with /dev/random, not with /dev/urandom... -- Andrey A. Chernov <ache@null.net> http://www.nagual.ru/~ache/
