It is necessary to copy pilot IDs of existing results to a temporary table before fetching undone jobs from the DB: Otherwise, due to MyISAMs table-level locking, collect_result_thread() will block in INSERT (SHOW PROCESSLIST state "Waiting for table level lock") until the (streamed) pilot query finishes. As one pilot query follows after the other, collect_result_thread() may even starve until the memory for the JobServer's "done" queue runs out, resulting in a crash and the loss of all queued results.
