In this example, we are simulating a file with `io.BytesIO`, which is a file-like object that lives only in memory, but lets us use the same interface.

The `--reload` option consumes much more resources, is more unstable, etc.

It helps a lot during **development**, but you **shouldn't** use it in **production**.
