---------------------------------------------------------------------

[~swegner]

It seems that we are hit by this flake ~once per month, most recently in https://builds.apache.org/job/beam_Release_Gradle_NightlySnapshot/197/

The symptoms are that a test suite started by `python setup.py nosetests` is passing but then
returns a non-zero exit code "-11", which we interpret as failure:
========================
Ran 1726 tests in 261.611s
OK (SKIP=324)
ERROR: InvocationError for command '/home/jenkins/jenkins-slave/workspace/beam_Release_Gradle_NightlySnapshot/src/sdks/python/target/.tox/py27/bin/python
setup.py nosetests' (exited with code -11)
========================

Exit code -11 may in some cases be a segmentation fault as per Stackoverflow Search.

This may be an issue with "nose" package, or some side-effects of some of our tests.

I suggest following further investigations avenues:
- Try to reproduce this locally, in a virtual environment, that has nose package and Beam
SDK installed via something like  `for i in `seq 100`; do python setup.py nosetests || echo
"Last exit code was $?"; done`.
- See if the tests that we are running make a difference whether the error appears.
- See if versions of nose makes a difference. 
- Reach out to nose maintainers.
