Dalek CLI not exiting after tests complete on Ubuntu

I've been having an issue with the Dalek CLI not exiting after tests have run on Ubuntu. After the test completes, it hangs for a few minutes and then throws a ERROR: Error: socket hang up and then exits the test.

Below is the output of the test: Note: The test is being called on a remote host.

I also get an error in the Dalek remote host command prompt.

I've tested this on Ubuntu 14.04 and 12.04.4 LTS and have had the same problem on both. The tests work fine on OS X. There are quite a few WaitFor calls (for dom ready) - could this be the issue? Really hoping there would be a built in call for this.
