emacs shell hangs on W32 with python

[emin . shopper]

Emacs seems to freeze when doing certain shell commands on Microsoft
Windows. The following is a simple example with Xemacs:

----------------------------------------------------------

[Xemacs version 21.4.19; January 2006]

Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.

h:\>c:\python25\python.exe -i
c:\python25\python.exe -i
Python 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import Tkinter
>>>
>>>
>>> t = Tkinter.Tk()
>>> 2
2
2

-------------------------------------------
At this point, python no longer accepts input. This example works fine
when starting python through dos instead of emacs. Note, I am not using
python-mode.el so that is not the problem. I also reproduced the
problem with GNU Emacs (version "GNU Emacs 21.3.1
(i386-mingw-nt5.1.2600)
 of 2004-03-10 on NYAUMO")


Is there any way to run python through emacs or xemacs without having
it hang or is shell support broken?

Thanks in advance,
