Hanging happens in 1.0beta evaluation with following use case:
* innodb_thread_concurrency=32
* ~50 client connections running short autocommit queries (UPDATE,DELETE,INSERT)
* one UPDATE with INNER JOIN, updating 'queue' table
* one DDL running: CREATE TABLE IF NOT EXISTS queue(...)
The DDL stays hanging in state: "Waiting for table metadata lock", killing this query resolves the deadlock.
