There's another possibility:
Switching from older SDK to 10.9 or 10.10 (I forget which) changed some order of operations.
Used to be: once window controller -close was called, everything went dead, and you could tear down table views, controllers, delegates, data sources in pretty much any order you wanted.
The new way: the frigging thing will try to redraw itself after -close, actually after invoking willClose on its window controller, and you have to tear things down in a very specific order.
