// this is done my calling System::Init(). Among other things, this is necessary to
// initialize the memory allocator. Similarly, System::Destroy must be
// called before program exist for proper cleanup. Both of these tasks can be achieved by
// simply creating System object first, allowing its constructor/destructor do the work.
