Gmaxwell pointed out that we could safely front-load all the key
pre-stretching. The spec has been updated to take advantage of this.
The user's password is now protected by 10,000 rounds of salted
PBKDF2-HMAC-SHA512, as well as the main KDF (which ranges from scrypt
2^14/8/8 to scrypt 2^18/16/16 and PBKDF2-HMAC-SHA512 2^16 to 2^21).
