 It would be nice to be able to load files from the local hard disk as
 error pages. Example of how it could look like:

 {{{
 sub vcl_error {
   if (obj.status == 503) {
     set obj.http.Content-Type = "text/html; charset=utf-8";
     sendfile "/path/to/error503.html";
     return (deliver);
   }
 }
 }}}

 Currently, this can be emulated with Inline C and
 fopen/fread/VRT_synth_page but an implementation in varnish itself would
 probably be much more efficient.
