Hmm, maybe Python is not relevant here, because we have,
in gdb/python/py-gdb-readline.c:

 /* Initialize Python readline support.  */

 void
 gdbpy_initialize_gdb_readline (void)
 {
  /* Python's readline module conflicts with GDB's use of readline
     since readline is not reentrant.  Ideally, a reentrant wrapper to
     GDB's readline should be implemented to replace Python's readline
     and prevent conflicts.  For now, this file implements a
     sys.meta_path finder that simply fails to import the readline
     module.  */

That still leaves open the question about non-GNU/Linux OSs, though.
