Description
If a balrogworker submit-toplevel task is re-run after all the balrog submit jobs, then the blob printed out by balrogclient here is on the order of 600k. This cause the log processing on scriptworker to hang (or something). Balrogscript currently writes logs synchronously, which meant it hung trying to write the log.
