// TODO(feliix42): Future Test Ideas
// - CPU Exceptions: validate that performing invalid operations (e.g., division by zero) leads to
// the correct exception handlers being called
// - Page Tables: validate/verify page table operations
// - Userspace Programs:Test userspace programs trying to perform illegal operations and see
// whether the kernel prevents them.
