A solid testing/benchmarking framework would quite seem like a useful
GSoC project as it would make it easy for casual programmers to dip
their feet into their personal bottlenecks, and it would make it much
easier to find worthwhile hotspots for future projects taking the
challenge of speeding up core and/or specific operations.

I've managed to make use of the outer sandwich layers: the prepare and
the evaluate stuff. I ran my own tests for benchmarking though.
It's enfuriatingly hard to get the stuff in the right directories and
with the right options, so that was already more helpful than it
probably should have been.
