What makes me think that this may not be that bad is the fact that post-resume, it will actually be hibernation code that will be unwinding things. So like this: prepare for hibernation, create image, suspend to memory (equivalent to hibernation failure of some kind, really), resume from memory, unwind from unsuccessful hibernation.

No?
