Sometime I'll finish the OpenJPEG speedup that I started:

That is an optimization with GCC4, however.

OpenJPEG is designed to be multithreaded, but it hasn't been fully 
implemented at the current version. The data structures are all setup 
for the task. There are just no calls being made to actually hand tasks 
over to worker threads.
