-It is similar to our `main.rs`, but uses a custom IDT called `TEST_IDT` and different `_start` and `breakpoint_handler` functions. The most interesting part is the `BREAKPOINT_HANDLER_CALLER` static. It is an [`AtomicUsize`], an integer type that can be safely concurrently modifies because all of its operations are atomic. We increment it when the `breakpoint_handler` is called and verify in our `_start` function that the handler was called exactly once.
