I sent a bug-report to the emacs list as requested and got an email
reply saying the message is being held for a moderator to look at.
Since the bug seems to be in the interaction of emacs with python, I'm
also cross-posting this to comp.lang.python in case anyone there can
help. (Note this bug shows up in all the versions of emacs that I have
tried including Xemacs and GNU Emacs 21).

The body of the bug-report is below:

I started emacs with -q did ESC-x shell and entered the following

>>> import Tkinter
>>> t = Tkinter.Tk()

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

Note that after the call to Tkinter.Tk() my python window freezes and
no longer works. Killing the Tk window does not help. I realize that
this may seem like a bug in python and not emacs except that if I do
exactly the same thing through a dos shell I have no problems (i.e.,
python keeps accepting input). Consequently, it seems like emacs is
doing something funky when running the shell that interferes with
python in a way that running the shell without emacs would not do.
