Is this a troll, or what?
I'm reasonably certain that all display drivers (as opposed to drawing code, such as
QuickDraw and Quartz 2D/3D) is done in kernel mode.
However, user applications, like office applications and browsers, should /never/
even be considered for running in kernel mode: 1) the kernel is resource limited,
compared to user applications; and 2) such applications tend to be too unstable, so they
could bring down the entire system if run in such a mode (it's bad enough that so many
hardware drivers are run in this mode [Apple is working on minimizing this as well]).
Is it just that this person longs for the bad old days of the classic Mac OS (and
DOS, and other older systems) where everything was run at the same privilege level on
the processor? Where everything could touch all aspects of the system at all times?
When anything could bring the entire system crashing around the user's ears? When all
applications could stomp on all other applications?
No thanks!
