Intuitively, it seems to me that those examples of classical "non-determinism" are radically different from the quantum ones, in the sense that quantum physics theorize non-determinism, while those situations are merely "left out" by classical theory. (I'm not a physicist, if any one reads this, I'd like to know what they think :)
By "left out", I mean that there are multiple solutions to the equations of motion which are compatible with the initial values of the situation.
I guess this could also explain why there is such an association in this thread between non-determinism and non-predictability ?

It's worth noting the distinction between a model and the thing the model describes. It's not "cheating" to note that while a model could admit multiple solutions only one could be valid in the original system.
In a very specific sense, eliminating the other solutions is still part of solving the model, just with discrete logic rather than e.g. calculus.
