BTW, is thread-safety really enough for Apache? I mean this way you more or
less just avoid side-effects caused by preemptive threading. But IMHO for
Apache you also need _asynchronous_ resolving to make sure the server
processes are not blocked out a thread inside the resolver library. Something
like GNU adns, BIND's libares, etc. I think is needed here...
