Although theoretically we should invoke "barrier.arriveAndDeregister();"
when catch ClosedSelectorException, but you're right it's not that
necessary, so removed.

No, we can not remove isOpen check, sel.select(..) could be interrupted
by sel.close() normally, at that situation, we need to exit selectLoop,
that's the code path before we fix the bug.

I have updated the webrev in place, please review it again.
