Please show us how you populate your arrays, because what you describe 
sounds wrong. Seeding to the same value should give the same sequence of 
values:

py> import random
py> random.seed(0)
py> a = [random.random() for i in range(10**6)]
py> random.seed(0)
py> b = [random.random() for i in range(10**6)]
py> a == b
True
