Comment (by hailin):

 Implemented approach number 2.

 To use it:
 First get the total num of root elements:

 $root_num = $walker->get_number_of_root_elements( $elements );

 Then, decide on the page_num, per_page, and call paged_walk.

 Eg, suppose $root_num = 35, and per_page = 10, so there are 4 pages:

 $walker->paged_walk( $elements, $max_depth, 1, 10, other_args_if_any );
 $walker->paged_walk( $elements, $max_depth, 2, 10, other_args_if_any );
 $walker->paged_walk( $elements, $max_depth, 3, 10, other_args_if_any );
 $walker->paged_walk( $elements, $max_depth, 4, 10,  other_args_if_any );
