Correct me if I’m wrong, but when I traced the code, it appears that `proc:
Self = super().start()` fork parent process to create the child process. If
the goal of the pre-import is to load modules in the parent before forking, it
might make more sense to place it before the `proc: Self = super().start`.
```javascript
DagFileProcessorManager.run()
└─ run_parsing_loop()
└─ while loop:
└─ start_new_processes()
└─ create_process(dag_path)
└─ DagFileProcessorProcess.start()
└─ proc: Self = super().start(target=target,
client=client, **kwargs) //fork
```
