Possibly.  That's why I asked:

  If so, where?

This seems all to be pointing in the same direction.  telnet does a
reverse lookup of the caller's IP address.  If named isn't running
correctly, it takes about one minute before it reacts.  

Are you permanently connected to the net, or do you have dial on
demand?  Otherwise you might find it better to remove the default
route when you take the connection down.  That way, named *should*
return immediately.
