8153209: java/nio/channels/AsyncCloseAndInterrupt.java fails throwing exception: java.nio.channels.ClosedChannelException
For JDK-8068693, 500ms is too short on busy system for channel to be closed or for thread blocking on IO to be interrupted, increase the time from 500ms to 10000ms. for JDK-8153209, it's a test regression due to JDK-8151582, do not sleep when running tests for CONNECT/FINISH_CONNECT, sleep for other test cases.
