This may seem like a dumb question from a technical point of view (it 
     has been ages since I did an operating systems course) but....
     
     Is it (or will it be) possible to freeze RiscBSD and then run RiscOS 
     apps for a bit and then return to RiscBSD? I guess that the entire 
     virtual memory needs to be frozen and I guess that you better disallow 
     unixfs whilst BSD is frozen but this facility would be extremely 
     useful.
     
     (I am not expecting anything from RiscOS to survive running RiscBSD - 
     only vice versa)
