- rename `util.job(threaded=True)` => `util.job(threaded_=True)`
- refactored BaseListener out of Proxy
- fixed bad call default argument
- default value can be a callable that will be evaluated lazily

- added `util.thread` for a threaded equivalent to `util.process`

- added super simple examples for each at the top of the README to illustrate
- fixed unpickleable bug TODO add test
