Confusingly, calling "random.seed(...)" is not enough.  A too quick check once 
gave me the impression that it was (the first call of random.random() indeed 
returned the same value), but in order to store/restore the complete state 
you need to use the provided functions random.getstate() and 
random.setstate() which return the state as a a 3-tuple of an int, a tuple 
containing 625 ints and a None here.
