srsly?!  I really wasn't expect that!

For anybody wanting a quick refresh, this is what hangs:
    cmd = "dir"
    proc = subprocess.Popen(cmd, shell=True,
        stdout=subprocess.PIPE)
    ret = proc.wait()
    print "2. return code: ", ret

ok, could you paste these 3 lines to the top of the main()
function, then run the result?  you'll need to CTRL-C when it gets
to step 2, but if this looks ok (please check log.txt) then we're
still good.

    cmd = "dir > log.txt"
    ret = os.system(cmd)
    print "0. return code: ", ret
