I'm uncertain on this point, but I believe that may be somewhat mistaken,
even if only indirectly.

Part of the priority table is something called "window boost", which near
as I can tell, serves no purpose other than to give a priority boost to a
graphical program.

There was a discussion quite some time ago about this (probably in OS/2
Programming, though perhaps not) involving Denis Tonn and Ivan Todorski.
Ivan was disappointed with the adverse affect on other-app performance that
a graphical window seemed to have.  He wiped out the window boost from the
priority table in the kernel (I'm quite sure he backed it up ), and the
problem went away.

So, in that limited respect, the kernel may be considered "aware" of a
difference between text-mode and graphical programs, though it's an
awareness that can be removed with a hex editor.
