I'd think rolling into a ball would keep you tumbling too long. If you were 
going fast enough the
centripetal force might extract your limbs anyway. ;o)
My personal experience is for low-ish speed stuff (offroading) I try to get my 
hands in my armpits,
and keep my elbows in. My instinct wants to put my hands out, and I have to 
fight that urge.

The one high speed pavement crash I had, I spent most of my time on my elbow 
and hip while my whole
body rotated. Really I was just along for the ride, hoping no one ran me over. 
Even though I wasn't
consciously thinking about it, I kept my helmet off the pavement the whole 
time, not a single
scratch on it.

FWIW, I plan on wearing a neck collar, that Simpson / Cart racing idea is a 
good one. I bet there's
got to be some cart guys that have physical crash techniques...
