You will always find people explaining to you how it can be possible if 
you really know precisely how python object model works. If you actually 
do, you can possibly read their technics.
But my short answer would be "No, there is no reliable way to reload a 
module".

Still there is 'reload' builting function you can call on any module, by 
you must understand that it won't affect any other object that the 
module itself. New objects created from that module will take effects, 
but all objects created before won't.
