Tracked down why we were accumulating lots of temporary files in the /tmp directories on the processing nodes.  It was a bug in unique_tempfile_name() where we were creating a temp file without a file extension, but then return the filename with the extension.  Really we should be using mkstemps to do this with a suffix properly, but that doesn\'t seem to exist on our Linux boxes.  For now I have reverted to using mktemp which doesn\'t create those pesky files.
