This mostly isolates the implementations for both of these. Now, everything here calls the method itself, not any of the external methods. Few driveby fixes as well: 1. Git now ignores archive/ again (it's a build artifact, and can be removed when updating `master`) 2. Since I had to rewrite most of the Deferred implementation, the new version passes one of the skipped tests, so it is now enabled.
