Subject: [PATCH] debug_script():  I changed this in haste before to take out
 the use of NamedTemporaryFile (which can't work for this function's purposes
 on Windows).  Leaving temp files behind wasn't a great idea either, though,
 so try to clean up.  At least the test suite no longer leaves any of these
 guys behind now.
