I think if you have (in your /etc/host.conf) bind listed before hosts (meaning it will ask the dns server before looking at the hosts file), it would delay if the dns server doesn't have a reverse entry for 127.0.0.1, which would take a long time.. But it still doesn't sound right.. I had some similar problems with ssh, and patched it, which fixed the (similar) problem for me..
