I should be more precise there...I'm not connecting to the FQDN of the 
local machine, but of the DD-WRT router in front of it, which NAT's the 
packets to the local system.  If I do some other "normal" telnet (like 
to the actual FQDN of the machine), I haven't been able to repeat the 
failure.

I didn't check a packet capture to see what is unique about the NAT's 
packets, but not sure if that's relevant or not.
