Warn about my quick benchmark? http://atrey.karlin.mff.cuni.cz/~pavel/quickbench.html I don't see what is insane about it. Yes, there might be more effective generators of random bits, but that is not the point, this is quick&dirty attempt at benchmark. Also people will use cat /dev/urandom > /dev/sdX (and similar) to clean hard drives. There should be no need to warn about that. (Performance is going to be disk-limited anyway).
