        # AddThreadSelectorEventLoop is used, because a race between
        # this thread closing the socket and the selector thread
        # calling the select system call can make this test flaky.

        # windows, making this check redundant with skipIfNonUnix, but
        # we sometimes enable it on other platforms for testing.
