It seems like a waste to have a machine with unlimited registers. 
At any given point there is only one set of registers active and other
registers are just sitting there. Instead, a better idea would be to 
limit the number of windows to, say two or three and do loads and stores
if you exceed the number of available windows. It might be a wothwhile
experiment to find out how many windows are optimum for running UNIX.
