Agreed; done.

python.el will use temporary files to communicate with the inferior
python process. These temporary files are never cleaned up.

To reproduce, simply run M-x run-python and check the temp dir. It has a
"py?????" file in it. Kill the buffer and repeat, such files will
accumulate.

The following simple patch will delete the file after loading it.
