Chain breaking...

I read Sheldon Brown's article on fixed wheel bikes and one of his warnings is that if the chain snaps it can somehow wrap around the rear sprocket causing the back wheel to lock, leading to potential disaster.
However, I've mentioned this to a few people and they say it's nonsense. anyone have any experience of this?

Anyway it's not something I'd worry about as long as you keep your chain well maintained, chains usually break because they haven't been joined properly or they're worn out, not because they're not strong enough.
Also chains shouldn't come off either, if it does then it's too loose!

Not something I worried about beyond my first two weeks of riding fixed.

The bike skidded for about 30 yards before it came to a stop. To everyones amazement I didn't come off and the rear tyre didn't blow either. Great save were words of praise from quite a few!
After some roadside puling and tugging we managed to free the chain which allowed me to continue on the ride. There were a couple of teeth missing from the front chainring (Alu) and a tooth missing from the rear sprocket. Also the rear hub had been marked and the rear chainstay on the frame. All-in-all a bit of a mess!
I was advised by some that one way to ensure this doesn't happen again is to remove the lockring. The theory is that if the rear locks up then the sprocket should unscrew itself with the rear wheel becoming free to spin. I am not too sure that this is good advice and I therefore didn't take it - Fom that day I simply ensure that I check the chain tension every time I ride.

On the commute this morning I took it easy - something wasn't quite right, the chain was slacker than usual (but just good enough), and occasionally creaked. "Damn axle creep, I'll see to it at work" I thought.
Well, I finish my commute going up Steventon Hill, followed by a flat bit on the fast road outside work. Got the bike to the bike sheds and found out why the chain was slack. One of the links was stretched and just on the limit of snapping, probably where I broke the chain to get it off for cleaning a while back and did a bad job of joining it back again. Glad I spotted it at work instead of spinning down the same hill on the way back. (Also glad I have spare links and a chain tool)
