Real nonsequential processes can be described in a consistent way if they are assumed to satisfy a certain density property. Density as defined in [1] can be interpreted as postulating that a ""global state"" consists of a ""progress snapshot"" of all single activities which constitute it. The present report shows that postulating density amounts to postulating that (a) each single of a processs is either infinite or has a first cause (but not both), and (b) each single future of a process is either infinite ofr has a last effect (but not both). This result is interpreted and applied to the question of Turingcomputability.
