the-knights-who-say-ni

On macOS, socket.getaddrinfo() no longer uses an internal lock to
prevent race conditions when calling getaddrinfo(). getaddrinfo is
thread-safe is macOS 10.5, whereas Python 3.9 requires macOS 10.6 or
newer.

The lock was also used on FreeBSD older than 5.3, OpenBSD older than
201311 and NetBSD older than 4.
