(i assume you meant "if everyone calls getaddrinfo and gethostinfo only")

any threaded software that calls gethostbyname() or getaddrbyname()
(et al) should expect that those functions are not, and never have to
be thread safe.

and NetBSD currently does not have gethostbyname_r()...

so, besides our getaddrinfo() and getnameinfo(), which existing
non-thread-safe functions need to be?
