Well, I did not forget anything. I just described the method as it was in
the reference I quoted. The author mentions that the case of a second
permanent shell may happen, but says it is too unlikely.
Another point is that DOS usually loads programs upwards from the bottom of
the memory, so the first parent-less process one finds is probably the primary
shell. Anyway, I think there is no 100% reliable way of finding the primary
shell in DOS other than INT 2E.
