duplicate processing within multisite-post-duplicator

[Jon007]

function mpd_duplicate_over_multisite()
contains the line:
$post_id = wp_insert_post( $mdp_post );

which is fine, except that the save post is hooked by:
add_action('save_post', 'mpd_persist_post', 100);

since mpd_persist_post needs to perform almost identical actions to mpd_duplicate_over_multisite (if there is a link) then these actions are duplicated, causing slowness and further problems.

well, this kind of can be solved with the existing filters I see, sample solution is:

function ink_avoid_duplicate_calls( $mpd_process_info ) {
	add_filter( 'mpd_persist_post_args', 'skip_duplicate_calls', 10, 1 );
}
add_filter( 'mpd_before_core', 'ink_avoid_duplicate_calls', 10, 1 );
function skip_duplicate_calls( $args ) {
	$args[ 'skip_normal_persist' ] = true;
	remove_filter( 'mpd_persist_post_args', 'skip_duplicate_calls', 10 );
	return $args;
}
