[issue15408] os.fork/os.popen behaviour change between 2.7 and 3.2

[Richard Oudkerk]

Richard Oudkerk <shibturn at gmail.com> added the comment:

Actually, if you replace

	print(os.popen("uname").read())

with

        f = os.popen("uname")
        print(f.read())
        f.close()

or

        with os.popen("uname") as f:
            print(f.read())

then things should work.  This is because f.close() waits for the pid.
