// RawHostResolverProc will eventually be a getaddrinfo() replacement.  It
// will construct and send DNS queries to the DNS server specified via
// --dns-server flag and will parse the responses and put it into a cache
// together with the TTL.  Necessary amendments will be made to cache and
// HostResolverProc interface to accomodate these.
