Summary: Popened file object close hangs in latest Cygwin update

Initial Comment:
Today's update of my Cygwin installation caused a long
running Python/Tkinter application to fail to start. 
Further investigation shows it hanging on a closed of a
popened file object.  The problem seems associated with
importing Tkinter:

===========FILE START=====
#! /usr/bin/python

from Tkinter import *
from os import popen

print "Here"
#grab a calander in case we need it
calpipe = popen("/usr/bin/cal -3")
caltext = calpipe.read(1000)
print "Middle"
calpipe.close()
print "There"

print caltext
==========FILE END=====

prints "Here" and "Middle" and then hangs.  Windows
task manager shows sh.exe and a copy of Python2.4.exe
sharing most of the CPU time.  If I kill those two
processes, the program finishes its output normally.

If I comment out the from Tkinter line, everthing works
fine.
