Forcing tests to manually configure the IDT just to save 8KiB of memory is a terrible tradeoff, and also leads to weird tests (multiple tests have deliberately relied on shutdown to indicate success), and hard-to-debug failures, e.g. instead of a precise unexpected exception failure, tests see only shutdown.
