r = array.array('l', os.urandom(2**size_exponent)) len_r = len(r)

r size should not depend on the size of a long. You should write something like:

sizeof_long = ctypes.sizeof(ctypes.c_long) r_bits = 8 r = array.array('l', os.urandom((2r_bits) * sizeof_long)) r_mask = 2r_bits-1

The final code will be in C and will use neither ctypes nor array.array. Arguing about this looks quite pointless IMO.
