Cache menu items

Is there a reason the 3DSecure menu items are all in the !$may_cache clause of the hook_menu? These menu items will be declared every time a page is loaded. Probably not a massive performance hit, but since there's nothing dynamic about them it would be better for them to be cached.

Find attached a patch that adds a $may_cache clause and puts the menu items inside it, rolled against the current recommended release (5.x-1.3). I've left the drupal_add_css in the !$may_cache clause (natch).
