All work here happens on a volunteer basis... and it seems
everybody was busy or not interested.

I've done that now.

Note that your prposed patch did contain a bit too many "copy &
paste" repetitions...  which I personally would have liked to be
written differently, using a wrapper (function or macro).

Also, let's assume on Linux, would there be a way to create a
small, say 1 MB, temporary file system as a non-root user?
In that case, we could do all the testing from inside R ..
