function media_flush_caches() {

  // Garbage collection for the {media_filter_usage} table. If an fid was last
  // recorded four months ago (minimum three months due to logic in
  // media_filter_track_usage()), remove it from this table while the filter
  // and field caches are being cleared. If the fid is still in use, it will
  // be added back to the table the next time check_markup() runs on that
  // content. This prevents fids from staying in this table indefinitely,
  // even if the post that references them is edited or deleted.
