Summary: popen4/cygwin ssh hangs

Initial Comment:
The following python code hangs on executing cmd2
(works with cmd1).
The commands works fine when executed on a shell.
I have the same problem with Python 2.3.4 and 2.4
(Windows).
I use the latest Cygwin binaries 


import os

cmd1 = "bin\ssh"
cmd2 = "bin\ssh -i id_dsa admin at myserver.com uptime"

def docmd(cmd):
    print "Doing %s ..." % cmd
    
    (stdin, stdouterr) = os.popen4(cmd)
    
    for line in stdouterr.readlines():
        print line
    
    stdin.close()
    stdouterr.close()
    print "Done."

if __name__ == '__main__':
    docmd(cmd1)
    docmd(cmd2)

Give me some advice for testing (popen, linux, ...).
