Comment(by strk):

 I've to correct myself, it takes 5 iterations to correctly node the above!
 {{{
 Iteration1: # nodes created: 3
 Iteration2: # nodes created: 3
 Iteration3: # nodes created: 5
 Iteration4: # nodes created: 5
 Iteration5: # nodes created: 5
 Iteration6: # nodes created: 0
 }}}

 Since IteratedNoder returns 19 output segments, many of which being
 duplicates, I'm not sure it's doing its work the way it's meant to.
