That is not true - you have access to a read-only file system
containing all of the files in the directory that you uploaded with
appcfg.py update (and don't appear in a "static" handler in your
app.yaml, doesn't match skip_files, etc.). The reason that this fails
is because the file is being opened for *write*, which is not
supported.
Cheers,
Brian
