[EVENTLOG]
- Log files which are opened when the eventlog service is started are permanent files and will only be closed when the service is stopped. Other log files are closed when their handle is closed.
- Opening a non existing backup log file must fail.
- Opening an existing backup log files opens the file for reading only.
