 The message loop thread is needed to avoid significant performance degradation at run time as logging calls are blocking calls and might take a significant amount of time. `LoggerImpl::PushLog` is a non-blocking call. It will put the log message into the queue and returns immediately.

+### Configurable time before shutdown
+
+To prevent missing logs after SDL shutdown, after receiving IGNITION_OFF signal SDL dumps all logs into the file system before shutdown. To control logs flushing process SDL logger has additional ini file options:
+
+ * Option to flush log messages before shutdown.(using `LoggerImpl::Flush` function)
+ * Option that specifies maximum time before shutdown.
+
+Logger recieves shutdown settings via `LoggerImpl::InitLoggerSettings(LoggerSettings)`
