-; While working on improvements to the region info analysis, this test
-; case caused an incorrect region bb2 => bb3 to be detected. It is incorrect
-; because bb2 has an outgoing edge to bb4. This is interesting because
-; bb2 dom bb3 and bb3 pdom bb2, which should have been enough to prevent incoming
-; forward edges into the region and outgoing forward edges from the region.
