Jv_RunMain() is not invoked since there is no Java main in Python.

But Ofer, initVM() is the PyLucene equivalent thing here. That function calls 
JvCreateJavaVM() and is invoked when the PyLucene module is first imported 
into Python.

Hence, to follow David's advice, you need to do your daemonization tricks 
before actually importing PyLucene.
