Of course programming C or C++ on such an OS could be quite
challenging (Write to (void*)0 and you mess up your Proccess
Information Descriptor).

The C/C++ standard does not require NULL pointers to be represented by all
zero bits either. The null pointer constant, (void*)0, might be translated
into 0xFFFFFFFF or some other value.
