Comment (by teor):

 Actually, we should distinguish between padding relay cells, which need
 randomness because they are relayed, and link cells, which don't need
 randomness because:
 a) they don't have any digests, so randomisation doesn't gain us anything
 b) TLS should protect their payloads from modification
