[Python-Dev] Status of PEP 3145 - Asynchronous I/O for subprocess.popen

[Victor Stinner]

Hi,

For your information, asyncio.subprocess.Process is limited. It's not
possible yet to connect pipes between two processes. Something like
"cat | wc -l" where the cat stdin comes from Python.

It's possible to enhance the API to implement that, but the timeframe
was too short to implement it before Python 3.4.
