It's taking ~30 seconds between the telnet and getting the banner line.
Watching it via Ethereal shows:

The reason why it's taking ~30 seconds to pull up an article is because 
Thunderbird is (for whatever stupid reason) making multiple connections 
while I'm reading.

I suspect part of the issue could be that inetd on your end is trying to 
do a reverse lookup on my IP and timing out -- alas, whatever service 
they have here has not set up reverse addresses in their nameserver.
