Comment (by yawning):

 For what it's worth, I'm of the opinion that the `AF_INET6` socket being
 created is probably fine, as long as the browser isn't rendered non-
 functional if `AF_INET6` isn't supported.

 This can be revisited if/when people want to write seccomp rules that will
 kill (rather than gently reject) proscribed calls, but I don't think
 that's realistic at the moment.
