Actually we would have to do the heartbeat before and after the setup.
So we should go with your version unless we add a tst_get_timeout()
function that would return the test timeout, which, given that the
timeout is stored in tst_test structure would just do:

static inline int tst_get_timeout(void)
{
	return test.timeout;
}
