If you only call it once without setting the seed, the rand function
returns 0 on the first call.  However, if you call it in a loop, say 10
times, you will see the value change.  Since the rand function is
deterministic, the same values will always appear.  Other than that, I see
no reason why you should always get 0 or 1.
