[Python-Dev] Warn about mktemp once again?

    Guido> Have we documented the alternatives well enough? 

I suppose we could document explicitly how to use mkstemp() in place of
mktemp(), but the difference in return value is fairly modest:

    >>> tempfile.mktemp()
    '/var/folders/5q/5qTPn6xq2RaWqk+1Ytw3-U+++TI/-Tmp-/tmpV_5OLi'
    >>> tempfile.mkstemp()
    (3, '/var/folders/5q/5qTPn6xq2RaWqk+1Ytw3-U+++TI/-Tmp-/tmpmS7K4T')

and the argument list is quite similar as well:

    >>> help(tempfile.mktemp)
    Help on function mktemp in module tempfile:

    mktemp(suffix='', prefix='tmp', dir=None)
    ...
    >>> help(tempfile.mkstemp) 
    Help on function mkstemp in module tempfile:

    mkstemp(suffix='', prefix='tmp', dir=None, text=False)
    ...

    Guido> In most cases NamedTemporaryFile will work, ...

It's API seems to be a bit farther from the mktemp API than that of mkstemp.
