Regardless of whether the programmer expects a random name or a
predictable-but-unique name, there are only a finite number of names to
choose from so the programmer must take into account the possibility
that the chosen name clashes with names that the programmer would prefer
not to be chosen.
This means an Emacs patch such as [1] is needed regardless of whether
Gnulib's gen_tempname is changed to be more random than it is. Although
it's true that the bug fixed by [1] is less likely if gen_tempname
generates more-random names, the bug can occur no matter what we do
about gen_tempname.
