New submission from Jack O'Connor:
This toy program:
import asyncio
@asyncio.coroutine
def main():
p = yield from asyncio.create_subprocess_shell('echo hi')
yield from p.wait()
asyncio.get_event_loop().run_until_complete(main())
Produces this output on Arch Linux under Python 3.4.3 (but not 3.4.2):
hi
Exception ignored in: <bound method _UnixSelectorEventLoop.__del__ of
<_UnixSelectorEventLoop running=False closed=True debug=False>>
Traceback (most recent call last):
