> In mod_python.py/util.py, line 169, we stream a file upload to disk only if its Content-Disposition header features a filename attribute. Otherwise, the file is streamed to memory, thus opening a potential DoS attack by uploading very large files.
> We should :
> 1) Always stream file upload to disk
> 2) Define a default maximum file size which could be overridable.
> 3) Allow for the user to specify in which directory file uploads should be made, with a default to a temporary directory / file.
