HELP: Strange behaviour of subprocess

Hi there

I have installed Cygwin to my w2k machine and use
Python to execute Bash -shell scripts. I noticed
that in script below parameter "shell=False"
causes raw_input() to fail; the only way to
stop script is to kill the Dos window where
it is run (The Bash shell runs OK listing
directory contents to screen).

Any comments anybody?

---script starts--
import os, subprocess, sys

     retcode ="c:\\cygwin\\bin\\bash.exe -c\
	/usr/bin/ls", shell=False)
     if retcode < 0:
         print >>sys.stderr, "Child was terminated by signal", -retcode
         print >>sys.stderr, "Child returned", retcode
except OSError, e:
     print >>sys.stderr, "Execution failed:", e
raw_input("press any key")

---script ends--
