[wp-hackers] cache_categories and category_cache

[Mark Jaquith]

As far as I can tell, $category_cache stores category info on the posts 
returned in $posts = $wpdb->get_results($request); (the posts being 
processed)

$cache_categories is just pretty much a dump of the $tablecategories 
table, including categories that aren't related to posts being 
displayed.  So while $category_cache is used for displayed-post-related 
stuff, $cache_categories is used for unrelated category stuff, like 
showing a list of all categories, or getting the name of a category by 
its id.

At least, that's how I read the code... I only just glanced at it now 
(personal PHPXref of current CVS)... but that seems to be the distinction.
