Description
Async replication Galera node crashes when the node shuts down while master node has active OLTP load. The crash only occurs when the node is configured with multiple slave_parallel_threads
As per Jan Lindström, handle_rpl_parallel_thread should make sure we do not go wsrep_after_statement too early on shutdown
