>I replied twice that I thought using the CM exit instead of O_TEMPORARY is okay for NamedTemporaryFile() -- but only if a separate implementation of TemporaryFile() that uses O_TEMPORARY is added at the same time. I want guaranteed cleanup for TemporaryFile() since it's not intended to be reopened.

At the moment, the TemporaryFile directly reuses NamedTemporaryFile for none-posix or cygwin systems.

Does it mean, that your suggestion to leave the O_TEMPORARY for TemporaryFile means, that NamedTemporaryFile needs to have a mechanism to know whether it was called as a TemporaryFile and then to have a different functionality in this case relative to the situation it would be called directly?
