-When a Node process crashes from uncaught exception, exits due to a signal,
-or exits of it's own accord we may want to write some final logs – particularly
-in cases of error.
-
-Writing to a Node.js stream on exit is not necessarily guaranteed, and naively writing
-to an asynchronous logger on exit will definitely lead to lost logs.
-
-To write logs in an exit handler, create the handler with [`pino.final`](/docs/api.md#pino-final):
-
-```js
-process.on('uncaughtException', pino.final(logger, (err, finalLogger) => {
-  finalLogger.error(err, 'uncaughtException')
-  process.exit(1)
-}))
-
-process.on('unhandledRejection', pino.final(logger, (err, finalLogger) => {
-  finalLogger.error(err, 'unhandledRejection')
-  process.exit(1)
-}))
-```
-
-The `finalLogger` is a special logger instance that will synchronously and reliably
-flush every log line. This is important in exit handlers, since no more asynchronous
-activity may be scheduled.
