  Aha!  Ok, see, I'm just not up to date with this DRI stuff.

  If we can do ioctl()s to /dev/dri and have this handled by the driver,
the latency is now much more reasonable!  Sounds like this is a good
possibility for a standard way to query the refresh status.

  But could this be a solution we could implement in general?
