Great, thanks for the info. Good to know, I'll be sure to use ULE when
7.0 is released. :)

Understood, just a data point. :) Probably a better one: ffmpeg
encoding H.264 content with -threads 8 is nearly 4x as fast as a
single threaded ffmpeg process, so it's scaling well at least for
ffmpeg (linked against pthread).
