How useful is glxgears as benchmark here? The X.org people has been saying
for ages that "glxgears is not a benchmark".

If you hold everything in the system constant other than the
scheduler, then it's a useful measure of the effects the scheduler has
upon glxgears, regardless of how well or poorly written it might be.

I suspect the X.org people are correct in regards how most people
would try to use it, which would be measurements against different
video cards, CPUs, etc.
