I'm seeing similar extreme slowness even on a local machine.
Particularly noticeable is that the monitor displayed on a qemu virtual SDL
console (i.e. the defaut) slow enough to be practically unusable. It's taking
the best part of a second to rendering a character.
This is on an otherwise fast machine that does not have accelerated X drivers,
which suggests we're doing something really dumb like reading from video ram.
I have confirmed that this is caused by r6336.
