# Some trickiness here. Let's explain:
#
# If we are not careful, retrieving predictions from the database and
# presenting them as a numpy array can result in a bad ordering,
# since the given matrix may not be 'ordered' by some criteria
# that can be easily represented by an ORDER BY clause.
#
# It will sometimes work, because without ORDER BY you will get
# it back in the table's physical order, which unless something has
# happened to the table will be the order you inserted it,
# which could very well be the order in the matrix.
# So it's not a bug that would necessarily immediately show itself,
# but when it does go wrong your scores will be garbage.
#
# So we simulate a table order mutation that can happen over time:
# Remove the first row and put it at the end.
# If the Predictor doesn't explicitly reorder the results, this will fail
