      found = file if !found and Pathname.new(file).absolute?
      found, stat = safe_stat(found)
      return found, stat if found

      paths.find do |possible_path|
        path = ::File.join(possible_path, file)
        found, stat = safe_stat(path)
        return ::File.expand_path(found), stat if found
