actually in-kernel telnetd (and perhaps rlogind) is in Solaris 2.4 and higher if I remember correctly, and the (ahem) express reason was that at least one large customer was screaming about their 8-way Sparc1000 crawling under 200 or so telnet connections and nothing else running on it... SunSolve bugreports are sometimes an enlightening reading. BTW an all-time favorite is Adrian Cockcroft saying "HP-UX can't have *this* POSIX-compliant _and_ running this fast. Or if they have, somebody go and steal how they do it !"... well, something very similar.
