The ideal would be an option when processing the source file, to turn
off file deletion. Like

texexec document.tex --keep-temporaries

So by default the source directory would be kept clean, but when
"debugging" the intermediate files would be available.

Or perhaps some option passed to \startGNUPLOTscript (or
\useGNUPLOTgraphic) if that is possible?

 \startGNUPLOTscript[example][keeptemporaryfile=yes]

That might be better otherwise debugging a big document could result
it hundreds of files.

Another possibility would be to put the files in /tmp.
