It was Linus Gerdemann in Stage 7:

"He came close to colliding with a race motorbike close to the summit, dodging round it at the final instant, then flirted with danger on the descent, cutting each corner to the limit, and adopting an extreme position in search of aerodynamics, akin to a downhill skier's tuck, but with his groin on the top tube. It looked risky in every way, not least for his chances of fatherhood."

From the UK Guardian site.

Now, lph, don't be trying this at home. You promised...

Gods, no. It sounds terrifying

In fact I can't imagine even being able to fit in there.

I did it once, just to see what it felt like... it was NOT in a race and it was on a very straight stretch of road with new paving and no cross streets (and no traffic!), so I never felt particularly endangered. It does feel pretty unstable to be down like that. I wouldn't want to do it anywhere even slightly sketchy.
