The secor.upload.on.shutdown feature worked fine if we were shutting down because we received a signal, but not if we were shutting down because a Consumer thread had crashed and the UncaughtExceptionHandler had called System.exit(1). In that case we'd get a deadlock and the program would never exit. Change the shutdown hook to do nothing if any Consumer thread called System.exit. The simplest way to implement this is to move the UncaughtExceptionHandler into the Consumer thread itself as a big try block, so I did that.
