Not sure that this is as elegant as what you are suggesting , can
the kernel schedule a user level routine to be executed when an interrupt
occurs? I guess on Windoze land this is called a driver call-back.
Just trying to prevent dragging the whole X server to the kernel --
Actually dragging the whole X server to the kernel is not a bad
