Agreeing with drkirkby, we should use temp directories.

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.
Don't know if mktemp is POSIX, but it's widely available. Of course from
Python you always have http://docs.python.org/library/tempfile.html Both
are much better than manually specifying /tmp.
> 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.
I don't consider it a user error, and I also don't like filling .sage with
lots of junk.
> 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.
True, and this ticket has been opened for far too long.
