Merge pull request from takluyver/daemon-streamcapturer...

Merge pull request from takluyver/daemon-streamcapturer Daemon StreamCapturer The StreamCapturer should die if the main thread crashes. On Shiningpanda, a failure in another nose plugin has been causing the tests to hang, because the main thread exits, but the StreamCapturer thread is still alive. Under normal conditions, the thread will still be shut down cleanly - it will only die a messy death if the main thread does.
