That's how it is displayed in my case. gai.conf is empty. Right now
i dont see, where this behavior comes from. I hope you understand
that i'm very cautious about patching upstream source as long as we
dont have eliminated all the doughts, where this problem really relies.

I can not confirm this either. I just enabled bindv6only and tried
to connect again to oidentd on ipv4 and ipv6:

cl-849.dus-01.de.sixxs.net (2a01:198:200:350::2):39062

oidentd 18443 oident 7u IPv4 48082508 TCP *:auth (LISTEN)
Now it binds two 2 single sockets but that's really no advantage or
disadvantage at all.
