The entire point of DNS prefetching is that it's supposed to make the
browser faster. If it's not doing that, then the right thing would be to
remove it entirely, not to add a configurable "be broken / don't be
broken" option.

But I'm pretty sure the problem is just that we're prefetching too much:
https://bugs.webkit.org/show_bug.cgi?id=41630. (Although I think it's
gotten a little better since then. I don't see the spurious "no such
host"s any more...)
