Plain multiple undo does not imply that it gets saved. In DesireData, the 
multiple undo is not saved, but if the server crashes, then it would be 
possible to restart the server while not restarting the client, and thus 
restart the server using the same unsaved patches and preserve the 
undo-stack as well. It's not implemented but it's not far from being able 
to do it.

It would be also possible to save the undo-stack in a file, be it 
separately or within the .pd file itself.
