I've been playing with the menu hooks, particularly with the Events module and noticed that changes are not reflected immediately and/or "linger" unless the corresponding cache record in the cache table is deleted.  Steps to reproduce:

1. execute DELETE FROM Cache statement in MySQL
2. modify $items array in hook_menu
3. invoke module/request new path (GET /new/path)

I have caching set to "disabled" in the admin > settings, but $may_cache is set to true; why is it caching it?
