I'm not sure I understand the problem.  Why can't the application that doesn't
need the window manager just use ginit() and pretend the window manager isn't
there?

As I understand it, the window manager doesn't steal any cpu cycles unless
the mouse is moving, and even then it doesn't use (eventually won't use?)
more than 5%(?).  Is it the amount of memory it uses?  How does stuff about
when to swap stuff out get decided?

The only other thing I can think of is that other people can run windows on 
top of the thing that thinks there isn't a window manager.  Is there a way to
lock other windows out?
