I think the issue is that although (pure Python) module objects *can*
get collected, it's hard to track down and delete all of the
references to the object. There's the module name itself, the
reference in sys.modules, references to the module in any instances of
classes defined by the module, etc etc etc. So in practical terms,
getting a module collected is hard.

C extensions are different again. I believe they don't ever get
collected (there's no C API for a full unload of an extension DLL, so
it can't be done cleanly - I think this is being addressed in Python
