Where do you see that? My browser claims only one mention of getaddrinfo on that page
"You can also use getaddrinfo and getnameinfo to obtain this information" which contains no mention of thread safety. The glibc documentation for getaddinfo http://www.gnu.org/software/gnulib/manual/html_node/getaddrinfo.html just refers to the POSIX specification http://pubs.opengroup.org/onlinepubs/9699919799/functions/getaddrinfo.html which states The freeaddrinfo() and getaddrinfo() functions shall be thread-safe.
