Indeed, looking at sources, the posix version uses the mkstemp/unlink
idiom.. but in win it uses a bit of hackery. It seems opened files
cannot be unlinked.


if _os.name != 'posix' or _os.sys.platform == 'cygwin':
    # On non-POSIX and Cygwin systems, assume that we cannot unlink a file
    # while it is open.
    TemporaryFile = NamedTemporaryFile

else:
    def TemporaryFile(mode='w+b', bufsize=-1, suffix="",
                      prefix=template, dir=None):
       ............
        (fd, name) = _mkstemp_inner(dir, prefix, suffix, flags)
        try:
            _os.unlink(name)
            return _os.fdopen(fd, mode, bufsize)
        except:
            _os.close(fd)
            raise
