Revert the change I6507e693fc929e03884f933bbda241f744d3a7c0. The
testtools bug was fixed, the "| cat" workaround is no more needed.
Fix for subunit (for testtools), workaround the eventlet bug:
https://github.com/testing-cabal/subunit/pull/14
Fix of the root cause in eventlet:
https://github.com/eventlet/eventlet/issues/248
The bug was limited to Python 3 and related to non-blocking stdout.

We don't see it right now in logstash as we fail with
a Segmentation fault (core dumped) because of other
issues. But will end up seeing it once that is fixed.
