#### Merging pull requests ####

Due to Guava's nature as a subset of Google's internal codebase which is

	go l.cleanupRoutine()
	return l
}

var logOnce = newLogOnceType()

// LogOnceIf - Logs notification errors - once per error.
// id is a unique identifier for related log messages, refer to cmd/notification.go
// on how it is used.
func LogOnceIf(ctx context.Context, subsystem string, err error, id string, errKind ...interface{}) {
	if logIgnoreError(err) {
		return
	}

In this example, the messages will be written to the `log.txt` file *after* the response is sent.

If there was a query in the request, it will be written to the log in a background task.

And then another background task generated at the *path operation function* will write a message using the `email` path parameter.
