    Metadata details:
    filename: lax_single_process_fs_flag.rs

  fn drop(&mut self) {
    use fs3::FileExt;
    // kill the poll thread
    self.finished_token.cancel();
    // release the file lock
    if let Err(err) = self.fs_file.unlock() {
      log_debug!(self.environment, "Failed releasing lock for {}. {:#}", self.file_path.display(), err);
    }
