The X server is not reniced nor are any of the called tasks. This is very
easy to reproduce by doing the following;
open two xterms, run glxgears from one and then 5 or so seconds after that
run an application which you can easily determine completion, such as
ifconfig. You will notice that the console app doesn't make much progress
and essentially get's starved.
