Reading this, I got the idea that to apply this on venti,one could put the text segment of the ventiserver into the unused part of the venti partition, and load the data log as the data segment. Probably, this would not work with production venti arena partitions, but for small (less than 2GB) ones.
What would happen to the data segment? It won't be written back to the program image, or else?
