Comment (by nickm):

 It looks like the main culprit here is the init_addrinfo() call, which
 tries to resolve our own hostname and cache the result.  I wonder why it
 was necessary to do that.  Does anything break if you remove the body of
 init_addrinfo()?

 DNSPort doesn't have anything to do with the Tor client's use of
 getaddrinfo as far as I know.  Not sure why you're seeing that.
