This is just an FYI copied from svn-src-head: https://lists.freebsd.org/pipermail/svn-src-head/2016-July/089328.html says the below. I'm just giving it somewhat wider exposure. Likely any replies should be to https://lists.freebsd.org/pipermail/svn-src-head/2016-July/089328.html instead of to this message.
