No. Messing with _res was always dangerous and since NetBSD went and
made incompatible changes, life became hell.
If we're going to do anything more sophisticated, or any surgery at all,
then my inclination would be to rip out all support for _res and libc
DNS handling and go straight to the getdns API.
We're past breaking point on any more vendor stupidity in _res.
