In TrueCrypt I noticed the option to encrypt a volume with multiple encryption algorithms i.e. AES-Twofish-Serpent. Would it be useful to encrypt something with the same algorithm multiple times? For example AES-AES-AES. I would guess if a flaw or backdoor in the algorithm was discovered this defense would be useless, but would it make brute force attacks harder?

EDIT: how is applying multiple iterations any different?
