Hi All,
Curious to see this in the docs for subprocess.check_output: "Do not use
stderr=PIPE with this function as that can deadlock based on the child
process error volume. Use Popen with the communicate() method when you
need a stderr pipe."
Given that check_output's implementation uses communicate(), how could
stderr=PIPE cause a deadlock in a way that wouldn't happen if you called
Popen.communicate() yourself?
cheers,
Chris
