Ah, that explains. Doesn't suite me though: I do run machines in an
assumption that bad guy is already inside. Saved me twice: I watched
attempts of elevation of privileges (unsuccessful) before I locked regular
user account that was compromised. So this doesn't suit me, alas, even for
backend servers. I guess I had too "strict" teachers ;-)

Thanks for clarifying!
