Tsocket.cpp addrinfo ai_flags = AI_ADDRCONFIG

While creating and using thrift based app we have found some problem on windows 7 which was not present on winxp. When we try to open socket with local_open() for the host name "localhost" getaddrinfo fails with 11004. What is important we do not have any physical network address as all network cards are disabled in the system. As I assume it is connected wit he flag AI_ADDRCONFIG. Why it is set by default? I wonder if I do remove it can it cause some problems? I would like our app to be able to communicate locally even if there is no external network available.

Hope to get quick reply, thank you.
