StringIO vs array.tofile() ?

The array's tofile method requires a file object (i.e. an object whose
type is types.FileType); a StringIO object is only "file-like".

Since this limitation is documented (it says file, not file-like),
this is a bug in your code. I recommend to use the .tostring method
instead.
