The basic issue I can see at the moment, is interactivity and
scheduling, 3D pipelines are getting longer, to efficiently schedule
multiple app on the GPU, we will start to run into the fact that the
DRM lock is somewhat akin to a sledgehammer, I'm sure this problem is
solvable but I think getting Xegl working is an easier direction.....

(for example running two glxgears shows obvious scheduling issues)...
