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.
