WP serving a cached get_categories result

Hi

I am running into a very weird issue. In my page I have a simple:

$args = array('taxonomy' =>'shorlist',
'orderby' => 'term_order',
'order' => 'ASC',
'hide_empty' => 0,
'parent' => 0
	);
$topLevelCategories = get_categories($args);

After I make some changes, I see nothing happened so I installed a SQL monitor. But for some reason the page does not run get_categories SQL queries at all. How can this be? Why is is serving some kind of cached query? Can I turn this off?

Thanks
