If we have to start programming like this because we don't trust our 
(ultimately, ourselves), then we're pretty much doomed.

If anyone is contributing code to qemu these days, chances are that his code 
get reviewed. We'll then spot those things and kick them out. That's the only 
reasonable way to get quality.
