Description

This is an example provided by @launchany on Twitter: https://gist.github.com/1036760

It appears to run a bit slower in 1.9 mode than 1.8 mode. After reducing the benchmark a bit, I did find that Array#join is slower, perhaps because it does not precalculate the size of the string. There may be other cases here that can be improved.

There is a more extensive bug that investigates join performance.
