Yes, but temporary-file-directory just returns the directory, you
still need to create the file itself.  And due to remote
communications, the window between these two events can be quite
large, so we can be a victim of a race condition with probability that
is too high.

That is why I thought that maybe a single function that actually
creates the file and returns its name could be better.
