A fluid jet with a finite angular velocity is subject to centripetal forces
in addition to surface tension forces. At fixed angular momentum, centripetal
forces become large when the radius of the jet goes to zero. We study the
possible importance of this observation for the pinching of a jet within a
slender jet model. A linear stability analysis shows the model to break down at
low viscosities. Numerical simulations indicate that angular momentum is
expelled from the pinch region so fast that it becomes asymptotically
irrelevant in the limit of the neck radius going to zero
