>>(a special .NET Virtual machine with super-lightweight user-mode threads)

My god , thats a terrible idea Sad...  one of plus of the windows kernel is its approach to multi thread.. you are purposing a way to create havoc inside an already butched kernel... ridded with shortcuts to improve gamming and graphics Sad

The original NT kernel was beautiful, a bit slow, but perfect in its original design, light years from unix.. now its a mix of hacks and tricks... Sad
What windows needs is to return to its origins an clean and Inspirated kernel based in very good ideas from VMS....
