It looks like I can make the code do what I want if I inherit from SourceLoader instead of InspectLoader. The get_data() method is used to execute the module, and get_source() is only called when the source code needs to be displayed. Even though inspect.getsource(module) works for InspectLoader, that source code is not shown by pdb or in tracebacks until we inherit from SourceLoader instead of InspectLoader.
