A parallel program, Dijkstra's "on-the-fly" garbage collector, is proved correct using analysis along the lines suggested by Francez and Pnueli for cyclic programs. The method is briefly reviewed, and the proof is compared to another proof by D. Gries, based on a method by S. Owickd. The differences between the two approaches are discussed.
