I'm using the spice client that comes in the default RHEL 6 
repositories. libjpeg-turbo is not installed as a system library 
anywhere I can find. If I am cpu-bound, it seems like it would be the 
qemu process running the VM. My spicec process does not utilize more 
than 50% of a cpu (as reported by top).
