The temp module provides a NamedTemporaryFile that can be reopened in the same
process on any platform. Most platforms use the standard Python
tempfile.NamedTemporaryFile class, but Windows users are given a custom class.

This is needed because the Python implementation of NamedTemporaryFile uses the
O_TEMPORARY flag under Windows, which prevents the file from being reopened
if the same flag is not provided [1][2]. Note that this does not address the
more general issue of opening a file for writing and reading in multiple
processes in a manner that works across platforms.

The custom version of NamedTemporaryFile doesn't support the same keyword
arguments available in tempfile.NamedTemporaryFile.

        Temporary file object constructor that supports reopening of the
        temporary file in Windows.

        Unlike tempfile.NamedTemporaryFile from the standard library,
        __init__() doesn't support the 'delete', 'buffering', 'encoding', or
        'newline' keyword arguments.
