asyncio errors on Windows

[wjwwood]

On my latest Windows job I'm seeing errors like this:

I think it might be related to this change?: 3684223#diff-64876ece93fadad6549af3a8bcb112c7R57

I'm not sure though.

I started http://ci.ros2.org/job/ros2_batch_ci_windows/301/ with #8.

[tfoote]

The ci finished with a lot of test failures. (83)

[dirk-thomas]

The problem is that the not succeeding tests are already there before: e.g. in http://ci.ros2.org/job/ros2_batch_ci_windows/299/

But since the nosetests are marked as "errors" and not "failures" the Jenkins xUnit plugin (configured for GoogleTests) does not pick them up as failing tests.

Therefore I would propose to merge #8 since it clearly fixes the invocation of a not existing method on Windows. And after that the tests still need to be fixed.

[dirk-thomas]

Since #8 only fixed the reporting (by not having tests with "errors" but "failures") I will reopen this.

The current state is getting build in: http://ci.ros2.org/job/ros2_batch_ci_windows/309/

Closed by #9.
