[talk] Is getaddrinfo thread-safe on NetBSD?

[A. Jesse Jiryu Davis]

Friends, the outcome of all this (I know you were on the edge of your
seats) is that getaddrinfo is thread-safe on modern Darwin, OpenBSD, and
NetBSD. I updated CPython to allow concurrent getaddrinfo calls on all
these BSDs:

http://bugs.python.org/issue25924
http://bugs.python.org/issue26406

CPython had already been fixed for FreeBSD. I leave Dragonfly BSD as an
exercise for the reader.
