Python 3 conversion failure on Windows

Browse Source 
Windows is not able to create a tempfile with NamedTemporaryFile and then
open it with a second file handle without closing the first one.  Added
code to close the handle, and keep the file around a little longer so it
can be reopened and rewritten to again.
