Most of the features already implemented for this release. The following is a list of the missing things in order to release the first beta tar.gz:
* Document "masterauth" in redis.conf, also merge the other related patch if it seems a safe one.
-* SETNX and MSETNX should use lookupKeWrite() in order to expire volatile keys when a write attempt is made.
VERSION 1.4 TODO (Hash type)
