And because of this, it's highly likely you can unwind through Win32 frames in 
our stack but cannot through Cocoa frames. So even if we did add unwind info 
to QtWidgets, there's a good chance it wouldn't make a difference.

But if someone does check that you can throw through Cocoa frames, then it 
would be worth having the unwind info, if nothing else to support the case of 
"emergency save in main()".
