-// 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.
