FWIW, I think an in-tree throw-away file is a better option, simply
because we _know_ that the working tree can be written (by the fact
that we can do "make" and have compilers write *.o and other cruft),
but we do not know if the CI environment allows us to write to /tmp
or /var/tmp or /usr/local/tmp and you do not want to run around and
see if there is a suitable temporary directory you can use.
