I've ran into a strange issue after trying to port a project to support py 3.x

The app uses a double os.fork to run in the background. On py 3.4+ it seems that when you have an import uuid statement it causes threading.threads to always return false on is_alive()..

Here is an example of the issue. You can see i've imported uuid. This script should fork into the background and stay alive for at least 3 loops (3 seconds) but it dies after 1 loop as self._thread.is_alive() return False??

This does NOT happen in py 2.7 or py3.3. Only occurs py3.4+
