close.2.patch
Simply calling close() is not sufficient if the recv(), or read() is blocking on another thread. That is because the recv() or read() will not be notified that the descriptor has been closed. This can only be done via shutdown().
This behaviour is different than on Solaris where simple close() is sufficient to kill recv() or read() on another thread.
See attached reproducer of this problem from additional info.
