I have been trying to figure out why "su" hangs for 30-60 seconds when I'm
not on a network with 1.5ALPHA_2. 
  I had assumed it was DNS, su looking for something to log, but after
mucking around with nsswitch.conf and resolv.conf a bit, I ktrace'ed it from
another window:

   523 su       EMUL  "netbsd"
   523 su       RET   poll 0
   523 su       CALL  close(0x3)
   523 su       RET   close 0
   523 su       CALL  socket(0x2,0x2,0)
   523 su       RET   socket 3
   523 su       CALL  connect(0x3,0x481d4e10,0x10)
   523 su       RET   connect 0
   523 su       CALL  sendto(0x3,0xbfbfa8c0,0x22,0,0,0)
   523 su       GIO   fd 3 wrote 34 bytes
       "]\M^]\^A\0\0\^A\0\0\0\0\0\0
        krb4-realm\^Bon\^Bca\0\0\^P\0\^A"
   523 su       RET   sendto 34/0x22
   523 su       CALL  gettimeofday(0xbfbfa614,0)
   523 su       RET   gettimeofday 0
   523 su       CALL  poll(0xbfbfa678,0x1,0x1388)
   523 su       RET   poll 0
   523 su       CALL  close(0x3)
   
  What's this, and how do I turn it off?
