Done; no change.  I don't think that was the problem - it'd
got past that and printed "sleep" from line 40. It seems to
be choking on line 41 - time.sleep(1):

$ python test-subprocess2.py
**** Begin testing 8
0. return code:  0
sleep
Traceback (most recent call last):
 File "test-subprocess2.py", line 48, in ?
   main ()
 File "test-subprocess2.py", line 41, in main
   time.sleep(1)
IOError: [Errno 2] No such file or directory

The time module is a .dll on Windows, so I changed the code
to:
   cmd = "dir"
   proc = subprocess.Popen(cmd, shell=True,
       stdout=subprocess.PIPE)
   while proc.poll() is None:
       print "sleep"
       cmd = "sleep 1"
       subprocess.Popen(cmd)
   print "2. return code: ", ret
   ans = proc.communicate()
   print "2b. result from communicate: "
   print ans

Don't know if this makes sense, but it reults in a never-ending
loop printing "sleep".
