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.

Hi, On core-mentorship someone asked about PEP 3145 - Asynchronous I/O for subprocess.popen. I answered that asyncio now has subprocess support (including non-blocking I/O on the three standard stream pipes), so it's not obvious anything else is needed. Should we change the PEP's status to Rejected or Superseded? Regards Antoine.
