Recent issues with master branch

I've been using `2.3.2` locally for a while, but my Travis-CI script was simply cloning this repo's `master` branch so always getting the latest code. Today, all of my builds started failing with errors such as:

```
/home/travis/.local/lib/python2.7/site-packages/ccm-2.4.4-py2.7.egg/ccmlib/node.py:509: UserWarning: Binary interface 127.0.0.1:9042 is not listening after 10 seconds, node may have failed to start.
```

This is my last successful build 3 days ago: https://travis-ci.org/thibaultcha/lua-cassandra/builds/164163446

It would appear that in the last 3 days, something got broken? The only commit I see in this lapse of time is 833f7894ecb4cfc0afceaa07342e85fcbd003e35, which, although I did not investigate the issue, appears like a good candidate.
