You'll have to use NSMenuExtra, not NSStatusItem, and make the menu item a bundle running inside the SystemUIServer process, not your own app. You'll also need code like that supplied by MenuCracker to get this to work.

My guess for there being two APIs in the first place: a menu extra crashing (or memory leaking) means the entire SystemUIServer process crashing or memory leaking — including other third party modules as well as system-supplied ones. With a status item, on the other hand, such a problem would only affect your own code.
