I'm not sure if you are agreeing with me or Leif there Robert - perhaps
you can clarify.
I was going to suggest that we should be using /tmp, but I did not since I
can see a disadvantage of it. NFS file systems have caused problems with
doc tests failing, especially if they are mis-configured. As such, it
would be better if a user tested Sage on the file system where it will be
used. By using /tmp they might get a false sense of security. That said,
using /tmp for temporary files has been the norm for years.
I personally think where reasonably practical, we should stop multiple
instances of running Sage tests interfering with each other. Although Leif
considers this a user error, it is one that a user might easily make.
But if it possible to avoid creating temporary files, then that should be
done. But I would imagine that requires more changes than just adding a
pid or hostname.
