Here is my understanding of the proposed procedure: 1. Replace modules in sys.modules with weakrefs 2. Run the garbage collector 3. Replace globals in any remaining modules with None 4. Run the garbage collector Is it possible for a del method to be called in step 4 or not? I am still unclear on this point. :-)
If an object is holding a reference to a module (e.g. self._sys = sys), then yes it should be possible because the reference has been creating a cycle.
