The data seems to be in a different order in the index array and in the 
data array returned by `find_duplicates`.

It is intended that find_duplicates guarantees that the returned indices 
correspond to the returned values?

Another question: the 'recfunctions' is not imported anywhere in numpy?

(BTW, it might be good not to keep commented-out code such as those 
np.knownfail decorators in the repository, unless it's explained why it's 
commented out...)
