      Description

      A coverage test hung with these two stacks:

            1 sched_yield,__wt_yield,__wt_session_get_btree,__wt_metadata_open,__wt_metadata_cursor,__wt_metadata_search,__wt_meta_ckptlist_get,__checkpoint_worker,__wt_checkpoint_close,__wt_conn_btree_sync_and_close,__sweep,__sweep_server,start_thread,clone
            1 pthread_rwlock_rdlock,__wt_readlock,__conn_dhandle_open_lock,__conn_dhandle_get,__wt_conn_btree_get,__wt_session_get_btree,__wt_conn_btree_apply,__checkpoint_apply,__wt_txn_checkpoint,__session_checkpoint,_wrap_Session_checkpoint
      

      The unit test that failed was test_backup03.test_backup_target.test_backup_target(7c), but clearly this isn't happening frequently or we would have seen it before.
