What do you have to lose?

On another note, what do you think of moving the vbench benchmarks
into the main numpy tree? We already require everyone who submits a
bug fix to add a test; there are a bunch of speed enhancements coming
in these days and it would be nice if we had some way to ask people to
submit a benchmark along with each one so that we know that the
enhancement stays enhanced...
