devdraw expects the messages to be delivered whole
in each write, so you'd have to introduce a buffer to
hold partial messages or be able to process partial
writes. much easier to tweak loadimage.
even easier would be to tweak drawterm so that it
ends up with a larger iounit. i'm pretty sure devdraw's
iounit is bigger and also that we bumped up the block
size in cpu (looks like 64 kB) for exactly this reason.
