IIRC it will return if there are only cleanups all the way up the stack. Then
you can use _Unwind_ForcedUnwind to unwind anyway IIRC (Ada uses this because
it always runs cleanups [*], unlike C++ which for some reason thinks that
cleanups don't matter if there is nothing else to do). I might be remembering
[*] For example a cleanup that shuts down the reactor.
