Before:
split.cc                                                   108r  107u
  0s        0mem    0pf
split_bfs.cc                                               192r  191u
  0s        0mem    0pf

After:
split.cc                                                    14r   14u
  0s        0mem    0pf
split_bfs.cc                                                78r   77u
  0s        0mem    0pf

The cache obviously works.
