 ### 1. Multiprocessing on Linux/Mac
  Multiprocess debugging on a Linux machine requires the `spawn` setting. We are working on improving this experience, see [#943](https://github.com/Microsoft/ptvsd/issues/943). Meanwhile do this to improve your debugging experience:
 ```py
-import multiprocessing
-multiprocessing.set_start_method('spawn', True)
+if __name__ == '__main__':
+    import multiprocessing
+    multiprocessing.set_start_method('spawn', True)
 ```
 Note: On Windows, the `multiprocessing` package uses "spawn" as the default and only option, so it is recommended for cross-platform code to ensure uniform behavior. If you choose to use `spawn` you may have to structure your `__main__` module like this https://docs.python.org/3/library/multiprocessing.html#the-spawn-and-forkserver-start-methods.

 ### 2. Breakpoints not set
 If you receive an error saying **breakpoint not set**, then look at your path mappings in `launch.json`. See Meta-Issue [#2976](https://github.com/Microsoft/vscode-python/issues/2976) for more details.
