[issue26731] subprocess on windows leaks stdout/stderr handle to child process when stdout/stderr overridden

[Sai]

Sai added the comment:

You can workaround this problem by adding a middleman process that sets 
close_fds=True:

############### childworkaround.py #################
import os
import subprocess

with open(os.devnull, 'w') as devnull:
    script = "import subprocess; import sys; subprocess.Popen(sys.argv[1:], 
close_fds=True)"
    proc = subprocess.Popen(['python', '-c', script, 'python', 'resident.py'], 
stdout=devnull, stderr=devnull, stdin=devnull)
