  Verify that the current cursor is that of the child.
  Undefine the child's cursor using xname.

    Verify that the current cursor is not the same as that of the default root window.
    Reset the cursor of the root window to the default cursor using xname.
    Verify that the current cursor is the same as that of the default root window.
  Otherwise :
    Set the root window cursor to a non-default cursor.
    Verify that the cursor was set correctly.
    Warp the pointer to the root window.
    Verify that the current cursor is that of the root window.
    Reset the cursor of the root window to the default cursor using xname.
