in my opinion, this is the best solution. I think that this is what
examples do: they run by default in $ESPRESSO_ROOT/tempdir or something
like that

- use (a subpath of) $TMP envvar which is often set in 'good' environments


I wouldn't bet on this one

- use '$$' aka PID if actual shell as distinguisher...

I am not sure I understand.  Thank you anyway for reporting this.

@Filippo:  I am not implying that we should replace all "include 'mpif.h'"
with "use mpi" at once: I just think that it is easier to deal with 1 line
of code than with 62 copies of it. There might be many machines around that
do not have a suitable "mpi.mod"
