[Note: This is beyond my range of expertise.]  Apparently it's useful to somebody in the case where the Printer cannot communicate with the output device.  In this case, the Printer cannot be shut down with synchronization.  However, the Printer can be shut down without synchronization, which allows any previously hung operations to complete.

Hmmm.  In our case, on Shutdown, "non-process-run-out"='true' is only valid with "synchronize"='true'.
