The current delays I'm seeing are a little excessive, especially
considering that the rest of the OS doesn't seem to have too much
problem displaying compiz and full-rate HD video.

The results of the profile look like:

I thought I'd throw oprofile at the task but as far as it's concerned
emacs spends most of it's time in mark-object and Fbyte_code and isn't
actually a significant proportion of the CPU time. Something else
seems to be going on.
