Summary: Previously, we would preallocate Node's with a child list of 4. We recently removed that logic (see diff below), and as a result, if you tried to access a Node's list of children before it had been allocated, you would crash. I added a simple check to protect from crashes, the operation of the check is O(1) so we shouldn't see a perf hit.
