Windows 8 it turns out can do very clever things when it comes to saving memory:
Starting with the Windows 8 Consumer Preview, whenever Windows detects memory pressure on the system, it will repurpose nearly all the memory that suspended Metro style apps would otherwise hold onto. Windows 8 can reclaim this memory without having to terminate an app.
