 Running consensus descriptors? Or is FetchUselessDescriptors currently
 only about fetching non-Running descriptors?

 FetchUselessDescriptors does that, and also one other thing:
 {{{
 int
 directory_too_idle_to_fetch_descriptors(or_options_t *options, time_t now)
 {
   return !directory_caches_dir_info(options) &&
          !options->FetchUselessDescriptors &&
          rep_hist_circbuilding_dormant(now);
 }
 }}}
 which causes update_consensus_router_descriptor_downloads() to short-
 circuit if true. So, no fetching descriptors (even running ones) if you
 haven't needed circuits lately.
