Please don't use tabs in code you post here. Many newsreaders
have trouble displaying them, and make the code look like it
does above (i.e. no indentation at all) which makes it hard to
understand.

You're looking for the Singleton pattern to ensure that only one
instance of your class is instantiated at a time. There's a particularly

I have a very large XML file that I load into dictionnaries defined in a class
located in a module that is imported in many places.
Since the loading process is very slow, I would like th
