This is the read-only companion to atiSaveConfiguration, reporting whether the asynchronous copy of the config database to NVRAM is still running or has finished. It matters because the save can take several seconds on a large configuration, and an admin scripting a save-then-reboot sequence needs to poll this value to avoid rebooting mid-write and corrupting the stored config. A management script would loop reading this object every second until it sees saveNotInProgress(2) before issuing the next command.
