This is mostly a precaution against an insanely huge address space that somehow starts coming close to the 2^32 root node size which would require something like 1.5 billion addresses. I chose unsigned long instead of unsigned long long since I do not believe it is possible to allocate a 32 bit tnode on a 32 bit system as the memory consumed would be 16GB + 28B which exceeds the addressible space for any one process.
