    Alright, Just got done with some testing of UT2004 between 2.6.23-rc1
    CFS and 2.6.22-ck1 SD. This series of tests was run by spawning in a map
    while not moving at all and always facing the same direction, while
    slowing increasing the number of loops.

    CFS generally seemed a lot smoother as the load increased, while SD
    broke down to a highly unstable fps count that fluctuated massively
    around the third loop. Seems like I will stick to CFS for gaming now.

    Below you will find the results of my test with the average number of FPS.

    CFS | SD
    UT2004 + 0 loops | 200 FPS UT2004 + 0 loops | 190 FPS
    UT2004 + 1 loops | 195 FPS UT2004 + 1 loops | 190 FPS
    UT2004 + 2 loops | 190 FPS UT2004 + 2 loops | 190 FPS
    UT2004 + 3 loops | 189 FPS UT2004 + 3 loops | 136 FPS
    UT2004 + 4 loops | 150 FPS UT2004 + 4 loops | 137 FPS
    UT2004 + 5 loops | 145 FPS UT2004 + 5 loops | 136 FPS
    UT2004 + 6 loops | 145 FPS UT2004 + 6 loops | 105 FPS
    UT2004 + 7 loops | 118 FPS UT2004 + 7 loops | 104 FPS
    UT2004 + 8 loops | 97 FPS UT2004 + 8 loops | 104 FPS
    UT2004 + 9 loops | 94 FPS UT2004 + 9 loops | 89 FPS
    UT2004 + 10 loops | 92 FPS UT2004 + 10 loops | 91 FPS
