No, a simple counter-example is a generator that uses the digits of pi. The digits of any transcendental number will do. I'll have to think about generator based on a square root. (Not about whether it would work, it would. But about how to implement it so that you don't have arbitrary pauses. Hmm. One task to generate the root? Managing priorities could be tricky.)
