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

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 Should we change the PEP's status to Rejected or Superseded?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.
