Yes, that was the idea. I thought it will be sufficient to copy the
pages with that code to double the resources to become independent from
the input-doc. But obviously it didn't work. There still has to be a
dependency.
Try to close the input-doc after writing the output-doc as it is done in
PDFSplit.
