Worker raises instead of exit with error

[alexandrevicenzi]

Function main_loop has this code:

try:
    log_file = conf.get("LOG_FILE", None)
    logger = logging.Logger("TaskManager")
    logger.setLevel(logging.DEBUG)
    if log_file:
        log_level = logging._levelNames.get(conf.get("LOG_LEVEL", "DEBUG").upper())
        kobo.log.add_rotating_file_logger(logger, log_file, log_level=log_level)

    tm = TaskManager(conf=conf, logger=logger)
except Exception as ex:
    raise
    sys.stderr.write("Error initializing TaskManager: %s\n" % ex)
    sys.exit(1)

If some exception occurs it's re-raised instead of executing the code above the raise line. This code is unreachable and it's difficult to know what should be the behavior.
