[issue31935] subprocess.run() timeout not working with grandchildren and stdout=PIPE

[Martin Panter]

Martin Panter <vadmium+py at gmail.com> added the comment:

This proposal sounds like a race condition. Closing the output pipe as a child exits means you risk missing recent output. On the other hand, if you don’t care about the output any more, close the pipe first and then wait for the child.
