I identified this infinite waiting for input:

         key = read_char (prevent_redisplay ? -2 : NILP (prompt),
                      current_binding, last_nonmenu_event,
                              &used_mouse_menu, NULL);

where NULL means no timeout. keyboard.c 9072

I don't call it an error, but just to make a point of a cosmic timeout. 
It originates from here.

The clue of the problem is different, because even when timeout is set 
to a number of 30 seconds, still wait_reading_process_output gets 
blocked until timeout expires.

I will dig more into it and definitely finish it in some way, perhaps 
reporting a bug in something.
