NamedTemporaryFile() can have an extra argument 'delete', which, if True
(the default), deletes the file after it's closed.

Try:

     temp = tempfile.NamedTemporaryFile(suffix='_suffix', 
prefix='prefix_', dir='/tmp', delete=False)


instead.

It's in the documentation:

http://docs.python.org/library/tempfile.html
