Yeah, you're right. I tried confirming what drum discovered with /whois, but what he experienced didn't happen to me. So I took another look with my packet sniffer, and this time, I got:

Code:
PRIVMSG Nick002 :Testing...
:Nick001!root@pool-71-177-xx-xx.xxxxxx.xxxx.verizon.net PRIVMSG Nick002 :Testing...
:evergreen.irc.simpworks.com 301 Nick001 Nick002 :I'm gone...

PRIVMSG Nick002 :Testing...
:Tampa.FL.US.Undernet.org 301 Nick001 Nick002 :I'm gone...
:Nick001!root@pool-71-177-xx-xx.xxxxxx.xxxx.verizon.net PRIVMSG Nick002 :Testing...

I guess the first time, when I saw the same packet order from both servers, I was seeing out-of-order arrival. Should have checked the sequence numbers...

So it's a daemon issue (if it's an issue at all). Sorry for the false alarm.
