There is a race condition between calling `make-temp-name' and creating the
file which opens all kinds of security holes. For that reason, you should

* If you are creating the file in the user's home directory.
* If you are creating a directory rather than an ordinary file.
* If you are taking special precautions as `make-temp-file' does. */)
