:It's taking ~30 seconds between the telnet and getting the banner line.
:Watching it via Ethereal shows:
:1 0.000000  TCP   3144 > nntp [SYN] Seq=0 Ack=0 Win=65535 Len=0 MSS=1460
:2 0.055418  TCP   nntp > 3144 [SYN, ACK] Seq=0 Ack=1 Win=4096 Len=0 MSS=1460

: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.

    Ok, please try it now.  I found a bug in my secondary nameserver setup
    which may be the cause.  It wasn't using port 53 for its outgoing
    (recursive) requests and the responses were being smashed by my firewall.
