Somebody whose opinions I trust told me that if Windows included null 
page protection, gobs of Windows own code would immediately begin 
crashing.  So there might be some reason why MS doesn't fix that.

(In case you didn't know: when Windows starts up, its kernel loads into 
the system VM as a DPMI client.  Imagine what would happen with null page 
protection...)
