Apache Spark 1.0 almost here. Is it ready with 16 (*) "unresolved blockers" in Jira? (* UPDATED x2)

UPDATE 2014-05-20: Matei Zaharia commented on the issue of combining map() and lookup(), stating that it's not within the current design to allow nested RDD functions, and that it's a feature he'd like to see added in the future. In the same Jira ticket, I had posted a workaround using join() which works fine.
