Ooops, I missed that init is declared static in noise_new(), so the same 
variable is used by every instance of [noise~].

I doubt if it would sound any different. Subtracting two identical noise 
signals should result in zero, but since it's very difficult to make two 
identical [noise~] streams it probably doesn't matter any more.
