Thanks for your reply. Using 'wb' instead of 'w' for the file mode
evidently makes this problem go away.
The mystery is that why does this work with plain lists *and* 'w' and
not with numpy arrays and 'w'. In other words, why is it that
numpy.array needs the binary mode while list does not?
Also, for my own edification, how did you know that my "pickle files
produced on Windows were contaminated by \r\n line feeds".
