  Less efficient than the original implementation in glib 2.53.2 that
  I wanted to port back, because this version iterates through the
  list twice. Though the original version depends on the internal api
  of GList (for example in terms on memory allocation), so I felt
  safer to reduce the problem to use public glib api only: g_list_copy
  and iteration.
