Summary of Debugging Session

When our program ran, it completed but the triangles it formed did not meet the Delaunay criteria. The sequences of insertions appeared to be correct. We hypothesized that despite the locking mechanism, some of the insertions interfered with each other. We checked this by looking for insertions that overlapped. We found three such pairs and, in examining the processes that executed those insertions, we determined that our locking mechanism essentially locked the sides of triangles but not their vertices.
