Apple has not made this easy, despite the fact that this new Resume feature causes binary incompatibility with several applications.
In my case, I made a wrapper around NSDocument's addWindowController: that adds this:
NSWindow* window = [inControllerToAdd window];
if ([window respondsToSelector:@selector(setRestorationClass:)] &&
[window respondsToSelector:@selector(setRestorable:)] &&
[window respondsToSelector:@selector(invalidateRestorableState)])
{
[window setRestorationClass:Nil];
[window setRestorable:NO];
[window invalidateRestorableState];
}
