Tweaking argument counts

By default, the action handler for triggering the asynchronous request will pass on up to 20 arguments. It's highly unlikely that you will ever need to change this value. However, if you wish to do so, override the protect $argument_count property:

<?php

class JPB_Task extends WP_Async_Task {

    protected $argument_count = 40; // WHO HAS THIS MANY ARGUMENTS???

    /*...*/

}
