Description Filip Pizlo 2017-01-08 14:00:52 PST

We should:

- Parallelize most DOM constraint solving.
- Make most DOM constraint solving concurrent.
- Make it cheaper to find and execute all of the DOM constraints.
- Reduce the number of DOM constraints by throwing away unobservable wrappers (like we used to).
