yes, it would be interesting to see Andrew's experiments redone for the
following combinations:

- your patch
- my patch
- both patches

in fact my patch was tested and it mostly solved the problem for Andrew,
but i'm now convinced that the combination of patches will be the real
solution for this class of problems - as that will attack _both_ ends,
both CPU hogs are recognized better, and interactivity detection
interactivity-distribution is improved.

but neither patch solves all problems. The typical DRI game just does
nothing but calls the DRI ioctl() and burns CPU time. So i'm convinced we
need one more way to help the kernel identify tasks that are important to
people - increasing the priority of those tasks programmatically is
certainly a workable solution, but there might be other solutions.
