how would you implement that in the face of multiple threads? you can't use TLS as it will have initialize your stack on first access of your malloc_stack in a given thread, which may or may not be safe to use in real-time-ish-contexts (I think it's definitely not on Windows, not sure on Linux)

I imagine you could you allocate it at the same time as you allocate the thread's own stack?
