Slightly off-topic, but I wonder if you could use mmap to give your app more address space? Create a big empty file, mmap it as writeable, then use a custom allocator to manage memory in the mapped space.
(This doesn’t actually give you more RAM; the mapped address space will tend to get paged out to storage so it’ll definitely be slower than real RAM, but it’s better than crashing!)
