 # Known bugs that can't be fixed here:
-#   - imp.load_module() cannot be prevented from clobbering existing
-#     loaded modules, so calling synopsis() on a binary module file
-#     changes the contents of any existing module with the same name.
+#   - synopsis() cannot be prevented from clobbering existing
+#     loaded modules.
 #   - If the __file__ attribute on a module is a relative path and
 #     the current directory is changed with os.chdir(), an incorrect
 #     path will be displayed.
