It is an interesting piece of technology, but IMO it is more trouble than it is worth, and most of the use cases for it are handled well by the Memcache protocol addition in MySQL 5.6: http://dev.mysql.com/doc/refman/5.6/en/innodb-memcached.html I orphaned it a long time ago, and nobody has stepped up to maintain, so I suggest just dropping it rather than chasing this RC.
