Wasn't really talking about different processes such as that. You 
can't run 1000s of different kernels in parallel. In graphical 
terms it'd be like queuing up a command to draw a single pixel. 
While that single pixel is drawing, the rest of the stack 
allocated to that kernel would be idle. It wouldn't be able to be 
utilized by another kernel.
