Using multiprocessing

When building as a standalone app, pytauri will automatically configure the following to support the use of multiprocessing:

ref: pytauri::standalone::PythonInterpreterBuilder

• Set sys.frozen to True
• Call multiprocessing.set_start_method with
  • windows: spawn
  • unix: fork
• Call multiprocessing.set_executable with std::env::current_exe()

---

What you need to do is call multiprocessing.freeze_support in __main__.py or in the if __name__ == "__main__": block.

If you don't do this, you will get an endless spawn loop of your application process.
