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:
Function Name Call Count Elapsed Time Average Time
=============================== ========== ============ ============
make-frame 2 17.385781 8.6928905
frame-set-background-mode 14 0.0370519999 0.0026465714

frame-char-height 14 1.199...e-05 8.571...e-07
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.
