Thanks for the patch. I vastly simplified the Theora multithreading 
prototype. Instead of copying the whole VP3 context like I did when 
modeling after the dnxhd encoder, I made a new structure that only 
contains a single int-- the slice number to be processed. Then I submit 
68 slices to the thread dispatcher for processing.

...and it still doesn't work quite right.
