I got some really interesting results when pinging a 6000 at it self:

   <sunset:/u/boote[31]> ping sunset
   <PING sunset: (128.117.8.71): 56 data bytes
   <64 bytes from 128.117.8.71: icmp_seq=0. time=-3. ms
   <64 bytes from 128.117.8.71: icmp_seq=1. time=1. ms
   <64 bytes from 128.117.8.71: icmp_seq=2. time=1. ms
   <64 bytes from 128.117.8.71: icmp_seq=3. time=1. ms
   <^C
   <----sunset PING Statistics----
   <4 packets transmitted, 4 packets received, 0% packet loss
   <round-trip (ms)  min/avg/max = -3/0/1

While the idea of a machine that can average 0ms is appealing it doesn't
hardly seem possible.  Notice it took -3ms for the first packet.  Has
anyone else seen this?  It's not a real big deal but it makes you wonder
what other bugs are just waiting to show themselves.
