Why are globals set to tls by default? and why is fast code ugly by default?

Go doesn't have a solution to preventing data races at compile 
time, they just say don't share memory. But what if you 
accidentally share memory? That is *very* easy to do in Go. You 
and your users are out of luck. All you can do is run the race 
detector and pray that you happen to test all the code paths with 
it that might have data races:
