Also true.

It is not an error.

From the Xlib document:

	3.2.  Window Attributes
...
	3.2.10.  Cursor Attribute
	
	The cursor attribute specifies which cursor is to be used
	when the pointer is in the InputOutput or InputOnly window.
	You can set the cursor to a cursor or None (default).
	
	If you set the cursor to None, the parent's cursor is used
	when the pointer is in the InputOutput or InputOnly window,
	and any change in the parent's cursor will cause an immedi-
	ate change in the displayed cursor.  By calling XFreeCursor,
	the cursor can be freed immediately as long as no further
	explicit reference to it is made.
