Seems like pyssh (which is very old AFAIK) uses signal. Looks like you're
creating the SSHController instance (which uses pyssh) not in the main thread,
and Python won't allow you to place signal handlers outside the main thread.
You can probably move the SSHContorller creation to the main threa
*Maybe* you can cook something with import hooks (see PEP 302). However I think
the easier option will be to distribute the .py files as well.
