Hhm.  There seems to be well-known problems with redirection
in Windows.  See for example
http://mail.python.org/pipermail/python-bugs-list/2006-April/032805.html

So I think this is the difficulty rather than the protection of Program 
Files.
Actually, applications _can_ write to Program Files.  What happens is
the output is actually placed in ~/AppData/Local/VirtualStore/Program Files
I guess this is so different users can use a common app, as well as
a protection mechanism - .exe files in VirtualStore can't be executed,
but .py files can.

It doesn't work - access is denied.

Yes, you need to create the directory, c:/temp, then edit the permissions
to give you write access or full control.  You need to be an administrator
to do this.

Having created c:/temp with the required permissions then this
works:

   cmd = "dir > c:/temp/log.txt"

Having done that I then get

$ python test-subprocess2.py
**** Begin testing 7
0. return code:  0
sleep
Traceback (most recent call last):
