Travis CI fails on py36-dev

Hi

I have pushed a PR for some components, but my Travis CI build keeps failing on py36-dev
I seem to get a timeout error…

How do I make this build successful for this PR?

Error in Travis buid:

__________ RunCoroutineThreadsafeTests.test_run_coroutine_threadsafe ___________
/opt/python/3.6-dev/lib/python3.6/asyncio/test_utils.py:471: in tearDown

        In non-CPython implementations of Python, this is needed because timely
        deallocation is not guaranteed by the garbage collector.  (Even in CPython
        this can be the case in case of reference cycles.)  This means that __del__
        methods may be called later than expected and weakrefs may remain alive for
        longer than expected.  This function tries its best to force all garbage
        objects to disappear.

Python 3.6 was deactivated for now.

Good to know. How do I restart the build of this PR?
I see no possibility to restart the build in Travis…

How do I trigger a new build?

I usually do a rebase on dev and push it again with -f. This should trigger a new run.

Hi @fabaff, I am trying to submit a PR and getting similar issues with Python 3.42. should I disable it as suggested above? Also can you help explain what those travis errors mean? I look at the output and have no idea what I need to change in my code to pass those issues.
Here is the output of my PR
