It's not in mesh.update(), the undo data is being saved by 
Window.EditMode(0), so as a quick hack for now you can stay out of edit 
mode during the whole realtime operation.  When I added this we were 
close to releasing 2.34 and something like that was needed.  It used 
intrr's undo push mesh call.  There's even a comment there (saw now) 
stating that a better method should be done after 2.34 (time flies...).

Yes, you're totally right.  We need to give bpython access to the undo 
stack, it's not hard, basically just push and pull with proper checks 
for stack limits.
