Maybe it could be as simple as saving a snapshot of sys.modules whenever importing of a module is begun, and if execution of its body doesn't complete, restoring the snapshot?
This is exactly what I thought of. It seems to be correct, also with nested imports, since this is a stack-like structure of undoable things.
