Not sure the version of dragonfly builder but the root cause of test flakiness comes from the kernel changes like the following:
http://gitweb.dragonflybsd.org/dragonfly.git/commit/727ccde8cce813911d885b7f6ed749dcea68a886

Simply dragonfly is dropping support for ipv6 ipv4-mapped address for some reason.

And Listen{,TCP,UDP} would not work consistently on some released kernels (4.0.x maybe?) and upcoming kernels.

Aha, on some 4.0.x version, setsockopt(IPV6_V6ONLY=0) finishes successfully but the kernel just pretends so, actually the kernel ignores that request and the state is still IPV6_V6ONLY=1.
