In my case connection establishes immediately (telnet client's messages
"Connected to..." and "Escape character..."), but the banner/greeting
(beginning from 220) is sent to the (telnet) client about 3 seconds after that.
Perhaps by default the delay is 1 second, in my testing it's 3 seconds
because I use rfc1413_query_timeout=2s and my desktop (with telnet client)
is behind a NAT, so connection to port 113 timeouts.

host_lookup=* shouldn't matter for second and followitg attempts
because of resolver caching.
