Also: todo, why the %*#(&%&# is top using 10% of cpu? Ubuntu's top is using 1%,
I should profile this and try to clean it up. (Did the manual stdio output
buffer setting help at all? Why was that done anyway...)

Also, todo: the unicode fontmetrics stuff was designed on the assumption that
combining characters go _before_ the characters they combine with, but I allowed
the elegant sane design of utf8 to cloud my judgement: unicode is insane garbage
that you have to keep parsing until you find the first character you CAN'T
display, and only THEN do you RETROACTIVELY know when you've hit the end of a
line. And if the data comes in slowly, your display device wind up repeatedly
redrawing the same glyph! That's BONKERS but hey, unicode! What is WRONG with
these...

Ahem. Todo item re last paragraph: cope. Update design/API to deal with... that.
