Among other things that happen when you log in, the system tries to
do an IDENT query back to the source of the connection and a DNS
lookup for the connecting IP address.  These should time out eventually
but could take a few minutes if a firewall drops the query or
response.  It might also look up the DNS name for the interface
you connect on.
