If I'm not terribly mistaken, the Kerberos code built into `su' will
at least try to do a DNS lookup to determine it's realm (if any).  If
your name server setup isn't as responsive as it should be, you'll see
a delay.  The Kerberos code path in `su' can be avoided by handing
`su' the `-K' option (which can be conveniently hidden away via a
shell alias).
