Well, if you have plentiful persistent RAM an application could easily "suspend" itself (on shutdown for example), and then resume running at a later point in time. The code would not have to think about this, since the entire state is just snapshotted. It's basically what machines do now when they "hibernate", except more effecient and could even happen if the power got cut.

Additionally I suppose your variables could also be persistent automatically. Though the biggest change I see is that software would never really need to completely close anymore when RAM == Disk. For RAM usage it wouldn't really matter if they were running or not, unless they delete data upon shutdown. To save CPU or other IO usage the application could simply be suspended.

Can't wait for the persistent memory leaks!

Or losing data on crash because load/save cycle is untested.
