void main()

    arr.length = 20; // And here we have a data-race.

                     // kinds of bugs.

I'm sorry, I know very little about race conditions. If you might 
explain just a little bit about what is happening here, I'd be in 
a better position to understand what you're saying. I really 
can't say anything other than please describe what this does and 
why it's a problem at this time.
