[issue12638] urllib.URLopener prematurely deletes files on cleanup

[Carl]

New submission from Carl <carl at carlbook.com>:

urllib.URLopener (or urllib.request.URLopener for Python 3) and user defined classes that inherit from these prematurely delete files upon cleanup.  Any temporary files downloaded using the .retrieve() method are deleted when an instance of a URLopener is garbage collected.

I feel this is a violation since the filename is returned to the caller and then silently deleted.  It is possible to simply override the .cleanup() method, but I feel this is not a good solution.
