On a run away/bolter, I don't jump off - my chances of no injury are still higher if I stay on. I don't attempt a one-rein stop - probably wouldn't be able to turn him and if I did we'd most likely topple.
I do try to break that head long, insane run by sawing on the bit. That most often works. Once I get a little give I start a large, safe circle, avoiding trip hazards. On only a couple occasions that didn't work and I changed tactics and I went into wild woman/banshee mode on their backs. They wanted to run, I gave them a reason! And we ran! A lot. But, they were problem horses who had gotten into the habit with weaker riders.
Bolting is not always caused by fear or bad manners, or excess energy, or pain... The trick, to me, is avoiding it in the first place or figuring what caused it, if it's a patterned behavior.
