I've noticed this failure too, thanks for fixing it. Changes look fine to me.

When a read operation completes then the completion handle awaits on a barrier and the test completes when there are 256 threads (plus the main thread) get to the barrier. The problem is that the test completely ignores the case where I/O operations fail and this happens periodically on Windows because the close may be abrupt. The 1-line fix to this is to do a shutdownOutput so that the connection is closed gracefully. The only changes are just to add additional diagnostic output and to ensure that a failure causes the test to terminate in a timely manner.
