Changeset [5d5c1ab3a24b07483d7bae0e4d3ae9f8a57357ee] by Matthew Draper

Replace Ruby.Generator with a much dumber implementation.

We only need to handle the case where we know all the generator values

in advance, so we can skip using Ruby's generator.rb: the old one uses

continuations; the new one uses threads... neither is likely to please

SpiderMonkey.
