 In the second case, let's say you dynamically generate a JSON object tree of a random complexity so you can't put a limit based on that. But on the other hand, you don't want your program to crash because the object tree doesn't fit in memory.
 The solution here is to determine how much memory is available, or in other words how much memory you can afford for the JSON object tree.
