Is "daemon.py" your main entry point? That is, is it the one you execute?
In that case, the module is initially imported as "__main__", not as  
"daemon"; if you "import daemon" from another file, you'll end with TWO  
different loaded modules for the SAME file (because "daemon" was not in  
sys.modules, so Python thinks it was not imported yet, and loads it again).
A rule might say: Your main script may import anything, but no one may  
import the main script.
