   I forgot to finish my chain of thought there.   
      
   For number 2, when the unprivileged call does an fwrite(),   
   it will go to code outside of its executable, that is   
   controlled by the OS, and then it's open slather. The   
   next function, also called fwrite, or similar, will do an   
   INT something where the privilege gets changed,   
   and then a little bit more assembler will handle that   
   and switch back to yet another function called fwrite,   
   or similar, but now running in the OS, privileged.
