aioeventlet

aioeventlet implements the asyncio API (PEP 3156) on top of eventlet. It makes possible to write asyncio code in a project currently written for eventlet.

aioeventlet allows to use greenthreads in asyncio coroutines, and to use asyncio coroutines, tasks and futures in greenthreads: see yield_future() and wrap_greenthread() functions.

The main visible difference between aioeventlet and asyncio is the behaviour of run_forever(): run_forever() blocks with asyncio, whereas it runs in a greenthread with aioeventlet. It means that aioeventlet event loop can run in an greenthread while the Python main thread runs other greenthreads in parallel.
