That it!!!! You gave me a idea. I just realize I have been thinking about
it all wrong. Its not looking at if the framebuffer is being accessed but
to keep track of all the processes that have mmap the framebuffer device.
When the accel engine is ready to go we put all the processes that have
/dev/fb mmapped to sleep no matter if its being access or not. One thing
that I would have to make sure that the same process thats being put to
sleep isn't also the one trying to use the accel engine.
