Then their talk about taking checkpoints of the memory is then basically 
qualified nonsense.
"All user state, including both data and running programs, are 
transparently saved on a periodic basis. In the event of system failure 
processes are resumed as of the last checkpoint. No special action or 
programming on the part of the application is required."
That is not a meningful or accurate description of orthogonally 
persistent single-level storage.
But, you are right, EROS have gotten the storage concept correct. They 
are just very bad at describing it. ;)
