357	buggy test_with_statement on Windows	cboos	cmlenz	"r1090 won't work on Windows, as it uses a !NamedTemporaryFile.

The doc says:
  '' Whether the name can be used to open the file a second time, while the named temporary file is still open, varies across platforms (it can be so used on Unix; it cannot on Windows NT or later). ''

So the `with open() ...` statement will fail.

Better use `mkstemp`, I think."	defect	closed	major	0.6	Expression evaluation	0.5.1	fixed
