Another nice patch =-) The only question that I have is, is it
possible to have more than OFBURSTLEN characters in the outq, and
if so, what happens to the extra charaters? Do they just stay in
the outq until the next poll cycle? I guess that it's hard to
get 12,800 keypresses in a second, though. The only other
problem that I see is that I remember ofwcons taking up a lot of
CPU when the polling cycle is increased. This was several years
ago, though, so it might be different now. Have you compared
CPU usage with your patch?
