It doesn't stop, actually. But Moz is *billions* (he he) times faster 
than IE on these string operations, and you get the impression that IE 
hangs. Just wait it out, if you want to see some really sad performance.

I stand corrected regarding the single versius double quote performance 
claim. Sorry about that, I'll check my sources better the next time.

I still want to know the "true" difference between single and double 
quotes, though. If any.
