Have the unwinder allocate memory with M_NOWAIT. The unwinder is used by DDB and we cannot know in advance whether it's save to sleep. It often enough isn't. We may want to pre-allocate space to cover the most common cases without having to use malloc at all, but that requires some analysis. We leave that for later.
