void test_abortion() {
	while (true) {
		int test = 0;
		unsigned lockVal = 0;
		unsigned * lock = &lockVal;

		__hle_acquire_exchange_n4(lock, 1);

		test = 1;
		_mm_pause();

		__hle_release_clear4(lock);

		printf("Test: %d\n", test);
		// 100% Transaction aborts
		// BUT
		// test is 1 after this
		// therefore, hle fell back to do a manual mutex lock
	}
