Standard Asynchronous Python

After seeing David Mertz's talk at PyCon 2012, "Coroutines, event loops, and the history of Python generators" [1], I got thinking again about Python's expressive power for asynchronous programming. Generators, particularly with the addition of 'yield from' and 'return' in PEP 380 [2], allow us to
