[issue3210] subprocess.Popen does not release process handles if process cannot be started

[Hirokazu Yamamoto]

Sorry for posting to closed entry, but I think handle should be closed in Lib/subprocess.py not in PC/_subprocess.c. I noticed following code showed strange error.

import subprocess

for _ in xrange(2):
    stdout = open("stdout.txt", "w")
    try:
        p = subprocess.Popen(["unknown"], stdout=stdout)
    except WindowsError:
        pass

// error

close failed in file object destructor:
IOError: [Errno 9] Bad file descriptor
