added a non-idiomatic ruby example, ran results

Abandon all hope ye who enter here! We are doing away with niceties like easy-to-read-and-maintain, idiomatic ruby in an attempt to speed up the ruby example. We might think of this as pulling out the passenger seats in a car, as well as all the padding on the driver's seat. Maybe pull the doors off as well...

Perl is still 2x faster, but this is looking better. (The concurrent go looks promising for real-world problems, though.)
