winnt win32process.createProcess with stdout to file ?

[Roger Upole]

You'll need to pass security attributes with inherit=True
to CreateProcess also, and the file has to be opened with sharing.
(win32file.FILE_SHARE_READ|win32file.FILE_SHARE_WRITE)
Also, you shouldn't have FILE_FLAG_OVERLAPPED set if you're
not passing an overlapped object into CreateFile.
