I don't really think this should be stored in the test directory.
Things in the test directory should be tests only. Why can't you just
make this an actual test and XFAIL if its not working or put it in a
README in the Cell Target? I believe other targets have READMEs in
their directories that mention potential optimizations or TODO items.
