[Python-Dev] Warn about mktemp once again?

Except for backwards compatibility: is there a good reason to keep
os.mkstemp at all?

The tradition is that all APIs in os expose the "system" calls as-is,
i.e. they don't try to adjust the result values at all. This has
the advantage that the caller can use their system's man page to
find out all details, and trust that the Python wrapper does exactly
the same.

For mkstemp, there are two special issues: the C API modifies the
string parameter, which cannot be exposed to Python as-is (hence
the two result values), and it isn't a system call (at least not
on POSIX), so it doesn't really need to be exposed, except perhaps
to also provide this on non-POSIX systems where a regular POSIX
implementation (in Python) would fail.
