Thank you very much Stefan for your reply, I'll study the sources you 
have pointed me to.

Could I allocate my resources in a "static" object (without publishing 
the type of that object so that I can't instantiate another one) linked 
to my module?
This way, when I stop the interpreter, the object will be destroyed 
calling its destructor.

There's something I'm missing?

Thank you, Luca.
