Actually, I think I see the answer to my second quesiton, which is that the models have strong pointers to the CBLDocuments, so as long as they aren't dealloc'd, the documents won't be evicted from the cache. I hope that thinking is right. Given that, it seems that an NSCache of CBLModels shouldn't cause problems, right?
