django.core.files.temp

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.
