Executing `fastapi run` starts FastAPI in production mode by default.

// termination sequence is called panicking and can be controlled by the
// built-in function recover.

### EventListener.Factory

In the preceding example we used a field, `callStartNanos`, to track the elapsed time of each event. This is handy, but it won’t work if multiple calls are executing concurrently. To accommodate this, use a `Factory` to create a new `EventListener` instance for each `Call`. This allows each listener to keep call-specific state.
