The problem doesn't seem to be resource exhaustion. It seems that Apple is using a hard-coded number specifically to detect a potential case of infinite CFRunLoop recursion and fail early with a clear message rather than let the app run wild. This doesn't seem to be tied to any limit I can check dynamically.
