One thing that occasionally happens to me is that I'm unable to switch
windows in X, or switch out of X, while the system is doing a lot of
disk IO and some part of the system that is swapped out can't be read
in, du to starvation. In cases like this I'd like to be able to switch
consoles and kill whatever program is causing the starvation. However,
to be able to do this I guess all changes of graphics state, or maybe
even all graphics operations, have to be performed by some priviliged
task, and I guess that may hurt performance quite a bit. I know there
were discussions on the KGI mailing list about this issue, but I think
they settled on a cooperative scheme.
