worker: do not swallow exception occurred in main process Before, SystemExit(255) would be most likely raised since the worker processes were terminated by the main process and the status would be set to 255 in response. We should instead re-raise the exception occurred first. It's pretty hard to debug problems like the issue 6035 with no traceback.
