There have been a couple of reports of this test hanging on Windows.
The test checks that the default channel group uses an unbounded thread
pool. 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.
The webrev with the changes is here:
