Sorry, the ministat output was mangled. I'll try this again with 80
columns instead.
Also, please disregard the buildworld comparison, as world has changed
since the previous 4bsd and ule runs, so obviously that's not a valid
comparison. Sorry about that.
Here are the ministat outputs for ffmpeg and sysbench, truncated to 80
columns instead. Hopefully that'll come through properly.
