Noble goal:

>                  const string& buildid /* unsafe */,
>                  string& artifacttype /* unsafe, cleanse on exception/return */,
>                  const string& suffix /* unsafe */,
> -                int *result_fd)
> +                int *result_fd, bool update_metrics = true)

.... but no need for an extra parameter.  When conn==0, we have
an internal request, so can use that as a flag.
