JDK-6380091 - IOException/SIGSEGV occurs during SocketChannel.close processing.
Description
test/java/nio/channels/AsyncCloseAndInterrupt.java is failing on Linux with 5.0u8 and Mustang since the integration of 6380091.

6380091 fixes a reliability problem that arises when a SocketChannel is closed before any I/O is done. That fix is okay but it exposes another bug in the finishConnect implementation whereby it doesn't record the thread while doing the poll - that is needed on Linux for signallying purposes. The implication of the is that finishConnect does not throw CloseByInterruptedException when interrupted.
