Public bug reported:

When running the py34 unit tests,
nova.tests.unit.test_fixtures.TestOSAPIFixture.test_responds_to_version
will block in epoll() for up to 900 seconds. This sometimes causes the
gate to timeout as the combined time of building the environment,
running the tests, and gathering the information can be too much
(despite all the tests passing).

The problem appears to be a deadlock/race in eventlet itself when
working with the same file from different greenthreads.

a fix is proposed and will be linked here momentarily
