Rather than this change, I think we should just rename `Random.create` (which is not officially documented) to `Random.createWithSeeds` (and require at least one argument).

I'm not sure in what context you would need multiple independent unseeded (ie, theoretically "truly random") PRNGs. Can you update the PR to do this instead?

Also, always use `===` instead of `==`. https://github.com/meteor/meteor/wiki/Meteor-Style-Guide#equality-testing
