More the former. Many of the di/dd splits in the code seem to me like
they start from very conservative assumptions about what "the hardware"
might be capable of, and hardware just doesn't vary that much.

If someone did want to drain that particular swamp, it'd be nice to see
Xv support in Xnest first, to ensure that the ensuing refactor is still
expressive enough to handle servers without pixmaps.
