init.cpp:1635 prints mapBlockIndex.size() without cs_main. This is technically a race (though it is rather inconsequential). At some point someone should fix this so tsan stops complaining.

/**
 * Private key encryption is done based on a CMasterKey,
 * which holds a salt and random encryption key.
 * 
 * CMasterKeys are encrypted using AES-256-CBC using a key
 * derived using derivation method nDerivationMethod
 * (0 == EVP_sha512()) and derivation iterations nDeriveIterations.
 * vchOtherDerivationParameters is provided for alternative algorithms
 * which may require more parameters (such as scrypt).
 * 
 * Wallet Private Keys are then encrypted using AES-256-CBC
 * with the double-sha256 of the public key as the IV, and the
 * master key's key as the encryption key (see keystore.[ch]).
