Ruby 2.1.0 in Production: known bugs and patches

Last week, we upgraded the github.com rails app to ruby 2.1.0 in production.
While testing the new build for rollout, we ran into a number of bugs. Most of
these have been fixed on trunk already, but I've documented them below to help
anyone else who might be testing ruby 2.1 in production.

@naruse I think we should backport these patches to the ruby_2_1 branch and
release 2.1.1 sooner rather than later, as some of the bugs are quite critical.
I'm happy to offer any assistance I can to expedite this process.

// Something like this. I haven't tested this file
@Injectable()
export class ApiService {

  constructor(public _http: Http, public _cache: Cache) {

  }
  // whatever domain/feature method name
  getModel(url) {
    // you want to return the cache if there is a response in it. This would cache the first response so if your API isn't idempotent you probably want to remove the item from the cache after you use it. LRU of 1
