# Sort streams by name before creating them so that we can have a

# to python 3.3 hashes were not randomized but after a security fix
# hash randomization was enabled in python 3.3 which made iteration
# of dictionaries and sets completely unpredictable. Here the order
# of elements while iterating `stream_dict` will be completely random
# for python 3.3 and later versions.
